It's pretty much confirmed with Jaffe getting excited over it so let's hope for another one.

God of War 4.

but thats something i can believe. something that would seem less believable yet more exciting would be Syphon Filter.

tbh i'm not sure if God of War 4 is a good idea. they've released 5 God of War games on the PS3. and i think they should wait until next gen until they do something with it.

could be this new brawler game rumoured or Metal Gear Solid 5 that has been said to be on the cards.

Debut means its a reveal.....I think it might be heavy rain spiritual successor from David Cage, I forgot the name.

The last Guardian.........

Probably Sony Smash Brothers, though I don't think SCE Santa Monica will have shifted onto next gen like Guerilla and ND most likely have, so there is a chance of that, or Heavy Rain 2ish

GTA V

You wouldn't believe it.

Because PS4 would make a great PS3 exclusive right? :P

Gears of war 4

Sony Smash Bros. Would be great to see if its real and some gameplay would be nice.

I think it would do atleast 4 - 5 million lifetime.  Thats pretty good for a PS3 exclusive.

lol
