So we know for sure we will get the following games shown at E3
So for the 100% likely list
Soul Sacrifice - recently announced for US release, and more info to come at E3
Assassins Creed 3 Liberation - shown on Gameinformer and to be released same day as AC3, definitely will be shown at E3
Ghost Recon Final Mission - got leaked with AC3 a while ago, so if AC3 came true this should too
Medal of Honor: Warfighter - leaked by french retialer
Need for Speed - leaked by french retailer, also this
Warrior's Lair - this game was shown before but has been missing in action for a while
Silent Hill Book of Memories - same as above
Killzone - we seen a glimpse of it on a trailer reel, I am sure now it is ready for a bigger showing
PS Battle Royal - I am guessing this will also be for Vita see this
LittleBigPlanet Kart Racing - same as above, as well as Sly 4 which was revealed before
Call of Duty - we have only seen a logo, but I am sure this will be one of the big reveals
Here are the games think that have a 50% chance to be shown
Quantic Dreams game - they are making 2 games for Sony, perhaps one of them is for Vita
Media Molecule game - they are making a new IP, maybe it is for the Vita also this
Square Enix Action RPG - this
Kojima game - he said all future games will for HD consoles and Vita, perhaps he will show his new game at E3.
Final Fantasy Type 0 HD - it just makes too much sense
Monster Hunter Portable 3rd HD - same as above, this game needs a western release so may as well give it an update
Resident Evil Revelations - cause Capcom love to port
Tekken Tag 2 - all other fighters seem to have made it to Vita, hell 3DS is even getting a Tekken
Invizimals - there last game was Reality Fighters. Vita needs its next AR game, Invizimals was quite a success in Europe for PSP so a sequel makes sense
Wild guesses
Infamous Vita - Sucker Punch is a huge team, I think they are maming a game for PS4 and a game for Vita
MotorStorm Legends - a best of MotorStorm game with the top courses from all 4 MotorStorm game to appear in this game, like Burnout Legends
Gran Turismo - Polyphonic hasn't done anything since GT5, maybe they are working on GT Vita
Syphon Filter - the series continues from the PSP iterations, Bend are still the creators, their next game after Uncharted
Skate - this game would work well on Vita, also the developers can copy and paste many assets from the console versions
Eyepet - Vita needs it's own Nintendogs clone, Eyepet should play that role, you can interact with AR, touch, and mic.
PSN/XBLA game ports - Super Meat Boy, Braid, Shank, Castle Crashers and etc for Vita
Other announcements
-White Vita

-PS1 Classics support

-PS1 and PS2 emulation streaming service also available for Vita as well as PS3 (also some PS3 titles also available for stream as well as game demos)
