PS3 wise i dont think there will be too much. Probably the PS1 & PS2 game streaming via Galkai which will be free for Plus members.
Ws hoping the next Gears of War would go Multiplatform but doesn't look like thats happening.
Timed Excluive DLC on GTAV will be the only Megaton that i can actually see happening.
Most of the new stuff will be games for Vita. Killzone and Call of Duty will probably be shown off.
I think just about everything has been leaked again.
Below is a Signature
Sony are stabbing their loyal family customers in the back - We have 3 PS3s and 3 PSPs all on the same IP address and all registered with Sony. Why can't we use them at the same time anymore?
