The announcement of the Mass Effect Trilogy was definitely bitter sweet for PS3 owners. Sure, we were happy to see that the original Mass Effect would be coming to the system, but EA was coy when it came to a release date, saying it would come out after the PC and 360′s November 6th launch.
I do believe nextgen is coming.
Watch Dogs, Castlevania: LoS 2 maybe.
MGS: Ground Zeroes and GTA V. maybe.
The Last of Us might be the second half, since God of War and Beyond are first half.
nothing confirmed, but those sound like mid-late 2013 to me.
I doubt Versus will release this gen, even Last Guardian is unlikely. Watch Dogs and MGS are likely nextgen games, GTA V is rumoured to be coming out in May.
Do not know much about Castlevania or LoS 2 though...
