You should tell that to Crytek.
I can't really see next-gen being anything too different to current gen games.
Other than improved AI (hopefully), more meaningless connectivity, smoother gameplay and bigger environments. The only thing left are visuals i.e, weather effects (again hopefully) and story. Maybe I'm being a bit cynical, but I can't see that much of a differance happening.
They'll just be slightly better games, nothing you couldn't find on the PC really.
You might have a vision, but that means nothing sir! I once had a dream, had to give it though, you heartless b******!
