Well, after everyone's gotten used to the PS3, make the next easy? I dunno, I just thought the PS3 and PS4 would be generally similar.. To keep backwards play in-tact. I don't care how hard it is.. And, it's not hard, it's just unflamilar.. But, I'm not a developer, so, I don't care.. I just want awesome stuff. Like Uncharted 2.
As long as it has backwards compatibility (PS1, and PS2 BC should be a given) I'll be happy. And, fix the triggers...
