Dear,
Don't expect to have a no-fanboy opinion on this thread.
The ONLY real advise I can give you is to evaluate the game librabry of both systems (current and coming).
There you will be able to make a choice because both consoles have pros/cons but remain very similar.
The rest is ... Fanboys Glorified Bullsh*ts and C/P of marketing blahblah ...
Evan Wells (Uncharted 2): I think the differences that you see between any two games has much more to do with the developer than whether it’s on the Xbox or PS3.
