I hope too...I do hope that Ariane 7 is going to be a heavy booster to lift a manned capsule to the Moon then Mars, Arianespace really need a competitor to the SLS and the next generation Chinese Long March heavy rocket.
Ariane 7 is already being worked on (under the name Ariane Next). This will be a reusable replacement for Ariane 6, in the same payload class. There are no plans to develop a larger rocket at the moment.
Europe is developing rockets according to its requirements.
SpaceX has redefined the standards for launchers, so Ariane 6 is a necessary step, but not the ultimate aim: we must start thinking now about Ariane 7
