What has been confirmed so far,
1. Anti-stealth capability
2. Sensor Fusion and Common Fire Control via high-capacity hidden networks between fighters
3. Longer range than F-22
4. Larger internal weapon capacity than F-35
5. Can be operated with unmanned fighters

IIRC Artificial Intelligence cooperation with the pilot was a hallmark feature as well.

i wonder if this will end up being something with a large delta wing.

The innovative stuff the Japanese have done is controllable ventral fins, which should provide pitch / yaw control at extreme AOA. This, well, looks like a FB-22 without even LERXes.
From what I can get, the F-3 is supposed to carry ASM-3s internally? Because I'm kind of wondering why they opted to choose that, especially considering how big the aircraft would be taking into account that the ASM-3 is about 6 meters long.
It's obviously a beast... But given that the F-3 would be considerably bigger than an F-35 that can fit around 4m long weapon, why not ?

From the Joint statement of Japan-UK foreign and defence ministerial meeting 2021:
So, this now called Jaguar.
The four Ministers endorsed the progress of the work of the Japan-UK High Level Defence Equipment and Technology Cooperation Steering Panel on defence equipment and technology cooperation. They welcomed the ongoing dialogue on Future Combat Air System (FCAS)/F-X at subsystem level in order to understand mutual requirements and the benefits of cooperation for enhanced technology and improved cost effectiveness. The four Ministers emphasised the importance of the research programme for the demonstration of a joint new air to air missile (JNAAM). They welcomed the successful completion of the Personnel Vulnerability Evaluation in 2020 and progress made on the Project for Cooperative Research on the Feasibility of a Japan and Great Britain Universal Advanced RF system (JAGUAR).

Think it's gonna be more than Radar's may also includes ESM and jammers too.

Yes, that's what Japan ATLA made. Common RF Antenna System.

Interpreting what's written :
It's a radar with simultaneous multi-beam and wide-angle radiation capabilities, enabling continous detection across all aspects leading to instantaneous detection of threats regardless of their position.
So, basically it feels like they are trying to mimmick VSRs but with much higher angular resolution, as what it basically does is radiate multiple pencil beams simultaneously across different angles to achieve such capability.
Future Missile Warning Technology.
Basically a Japanese equivalent of DAS system, so your typical EO MAWS with IRST capabilities.
conceptual diagram
RCS measurement of conformal sensors
HMD used for the testing of the system.
Diagram of how a C-2 transportation aircraft will be modified to accommodate the sensors to test the system.
Just like EO-DAS, it consists of 6 EO/IR sensors, which the information gathered by these sensors will be processed via fusion engine resulting in unified picture of individual threat levels and tracking data, and will be projected to the pilot on the HMD. Positional distortion will be corrected corresponding to the position of the pilot's head.

Describes what Ares wrote in page 5 of this thread. Seems to be that some of those images he uploaded aren't accessible anymore so reuploading.
Stealth testing from front and behind, high altitude testing and control function testing carried out in Sapporo
Currently researching ways to apply adaptive cycle to XF9 (https://web.archive.org/web/20200108101011if_/https://www.mod.go.jp/atla/data/info/ny_kenkyu_koukuu/pdf/kouji/kouji02-004.pdf）

Few other information regarding F-3 published last year. Maybe it was uploaded on this thread but I haven't seen it.
Development timeline
"Intended to replace F-2 starting from 2035"
From above (green) to below (yellow) :
"preliminary and detailed design"
"EMD prototype production"
"ground testing"
"flight testing (testing to continue after this timeline for the development of additional and improved capabilities)"
"manufacturing of first mass production model"
Current schedule regarding the future fighter development
"System integration contractor (ie main program contractor) to be chosen December this year (2020)" - MHI selected
"Planning to reach an agreement with the US and UK for the international cooperation and to lay basic structures of the development schedule" - LM selected as system integration and airframe design TAC, NG to support the development of data link with Japan-US interoperability, co-development of radar with UK (probably BAE) and ongoing negotiation over possible co-development of the engine (RR)
from left to right and above to below (in a reading order) :
★"deduction of rough estimation of program cost and schedule"
★"announcement of government budget for 3rd year of Reiwa (CE 2021)"
"reviewing the methods of contract and development system"
"selection of system integration developer"
"conceptual and preliminary design" (continuation from DMU probably)
★"selection of international partner"
"agreement with the US and UK (specify the areas of cooperation)"
"detailed adjustment of international cooperation with partner nations (US & UK)"
Ways to enable the higher level of (system) integration in the future fighter jet program
"While developing the legacy aircraft such as F-2 or P-1, MoD has contracted individual system providers (i.e. multi-prime) for each components such as the airframe, engine, avionics, etc. Due to such reason the interconnection and cooperation between these system providers were limited."
"Since the advent of 5th generation fighters, it was crucial to achieve higher levels of integration within the whole avionics architecture and system, thus it was necessary that coordination between the airframe, engine and avionics to achiever higher levels of low observability. Therefore it is important to set up a development structure which is suitable for the realisation of such higher levels of integration."
From left to right, each aircraft followed by another :
F-2
MoD grants contract to each prime contractors, namely MHI (system integration, in sky blue), GE (engine importation, in green), Mitsubishi Electric (radar and EW, in green). The sub component suppliers (in green) then supply the components to MHI without further cooperation.
P-1
MoD grants contract to each prime contractors, namely MHI (system integration, in sky blue), IHI (engine, in green), Fujitsu (photonic radar, in green), Mitsubishi Electric (self protection system, in green). The sub component suppliers (in green) then supply the components to MHI without further cooperation.
X-2
MoD grants contract to prime contractor, MHI (system integration, in sky blue), who then contracts sub component supplier (selected by the MoD), IHI (engine, in green). IHI provides technical support to MHI for the integration of the engine to the airframe.

T/R ratio (AB thrust) development comparison made by ATLA. Figure for F119 is an estimate. The trendline after XF5 should flatten out since the performance testing of XF9 (sized right at the middle between F414 and F110, thus with estimated weight of around 1,500 kg, it should have T/R of almost 10) started only after 2018. Makes sense as they are getting closer to leading edge technology of the US and catching up to Europe.

That kind of putting Russian engines like 117S (8.75) in about the same ballpark as M88's while the Izd-30 is near or at same place as the EJ-200.
