Come on now. I know you're worried about Dante not being platinum blonde anymore but that's also the only thing you need to worry about.
If you played Enslaved you'll know that Ninja Theory know how to make amazing, cinematic experiences and you should rest easy, knowing that this game will be seriously cool. Hell, Jeff Gerstmann said on the latest bombcast that it looked cool and he's seen more of it than we have. So don't be afraid of change and give the game a chance.
