What you see in today's tech demos, takes 3-4 years at least to get into games
The first Unreal Engine 5 games will be out sooner than that. Development is also faster with UE5.
So they will definitely do that if you finance the endeavour.
I think about 50 millions will do. Are you in?
Yeah I think Frontier will keep using their own Cobra engine, but if they don't upgrade the engine they'll go out of business. Tech upgrades should hopefully appear in ED as well.
