Possibly, but probably not. GTA just sells way too much on two platforms than one. Exclusives are usually either first party, or semi-new IPs... almost never a third party well known game....except for mgs4 that is...
Anyway, for my predictions:
New slim model
PSP trophies
PS3 DVR
PSPGo price drop
PS3 price drop maybe move bundle with 2 controllers and eye for 350-400
New valkyria chronicles
Demon Souls 2
New Tales game (not the badgenome one)
PS2 game firmware (long shot)
PSP2 Phone
Star Wars game
FFv13 gameplay or at least a new trailer that will disappoint everyone
Killzone 3
Resistance 3
Last Guardian
Some kind of music streaming program like pandora
PS4!!! :P
At least 4 new IPs
lots of move stuff.
kevin butler making at elast one fart joke.
EDIT: also lots of statistics and DLC
