Some of your predictions are what ive been thinking but here we go:
Nintendo:
Pikmin 3 and NSMB Mii fully revealed (and obviously will be Nintendos launch titles)
Nintendo announces a mini-game collection featuring the demos from last years E3 (Either free with console or to buy).
Starfox for Wii U revealed
Zelda: ALTTP 3DS revealed released May 2013 (i think its a remake not a new game)
Eternal Darkness 2
Wii U graphical power is the same as PS3/360
Luigis Mansion 2 gets October 2012 release, Animal Crossing December 2012 and Paper Mario November 2012.
and thats it..i think Nintendo wont show no-where near as much as people are thinking.
Sony:
A new Uncharted for Vita
More Vita titles are shown then PS3 games
Battle Royale and LBP: Karting can be played on both Vita and PS3
Killzone Vita unveiled (may make Christmas 2012)
Call Of Duty Vita isnt a FPS shooter but a RTS
Jak & Daxter PS3
Microsoft:
Next Generation console shown for the first time, although its a long way off..will be called the rumoured 'Infinity'
Kinect titles take a little bit of a back seat as Microsoft show an array of First-Party titles they've been keeping under their belt.
Alan Wake for Infinity shown in reel
Perfect Dark Infinity shown in reel
Microsoft enters the handheld market!
Lastly...Shenmue 3 will make an appearance (ive had a vision).
