Sony's legitimate possibilities have more weight IMO than the others.
God of War, GT7, Horizon, Media Molecule's New IP, that's without going crazy on the expectations, like The Last Guardian and Agent making a reappearance, which they very well could do.
Uncharted 4 will no doubt have new gameplay and probably it's release date.
Sony London could have a new Getaway game.
Sony Bend has a game, rumored to be an open world horror title.
Sly Cooper has a movie coming out next year, so there could be a game for that.
Resistance was recently trademarked again, Guerrilla Cambridge could be working on that or a new Killzone.
Maybe Motorstorm, a Wipeout or even an Exclusive Ridge Racer.
All possible for PS4.

Microsoft will probably have Halo 5, Scalebound, Crackdown and Phantom Dust gameplay, Forza 6, maybe Gears of War 4 too.
Extremes could be a Conker, maybe Banjo, Battletoads.
-----------------------------------------------------------------------------------------------------------
Nintendo will have Starfox and Zelda gameplay.
Maybe a new Metroid, Fire Emblem, F-Zero
Extremes could be a new core 3D Mario game, a Pokemon Open World game.
All parties can have plenty of surprises.
