A smaller bit of that sheet has been floating around gaming blogs for days now, and even from that snippet people knew it was fake. Now that you can see the whole thing, there should be no doubt in anyone's mind that it's fake. I could point out the many obviously fake things, like Mass Effect 3 being exclusive to Sony, but I really only have to say one thing to prove my point:
Rogue Warrior 2
actually, it doesn't necessarily mean its Sony exclusive... If i remember correctly only Mass Effect (1) had an exclusivity clause with M$... so it could just be Sony showing the 3rd, just like M$ displayed Beatles Rockband, MW:2, and FF:XIII
rogue warior 2 is a bit curious though. And the Legend of Zelda: Fall of Hyrule seems a bit cliche, since most zelda games deal with Hyrule being overrun.
--edit--
didn't see exclusive next to the names... probably fake
