These are really optimistic. Sorry if they suck. First off: no next-gen console reveals for Sony or Microsoft.
Sony
- PlayStation Vita broll: Persona 4, Soul Sacrifice, Tales of Innocence R, DJ Max Technika Tune, Dragon's Crown, Street Fighter X Tekken, Phantasy Star Online 2, Call of Duty, Assassin's Creed, BioShock Vita concept art, Killzone, etc.
- New PlayStation Vita titles from your favorite IPs (maybe God of War or Jak). Possible new PlayStation 3 reveals will have PlayStation Vita version.
- PlayStation Vita price drop to compete with 3DS.
- The Last Guardian dated/release windowed.
- Final Fantasy Versus XIII dated/release windowed.
- Final Fantasy X HD first look.
- PlayStation All-Stars Battle Royale: new character reveals, I'm guessing at least one will be very unexpected. Noctis from Final Fantasy Versus XIII, for example. Except not him because my dreams weren't made to come true.
- God of War: Acsension release date/showcase.
- The Last of Us release date/showcase.
- At least a couple new PlayStation 3 exclusives/third-party multiplatform game exclusive bonuses.
- More PlayStation Move games.
Microsoft
- Halo 4 showcase.
- New Kinect title announcements.
- Fable: The Journey release date/showcase. It will be reiterated in some shape or form that it is not an on-rails shooter.
- Ryse release date/showcase.
- Call of Duty: Black Ops II showcase. Will reiterate that Xbox 360 gets new map packs earlier than everybody else.
- Resident Evil 6 showcase.
- More Xbox LIVE applications.
- Big Xbox LIVE Arcade focus: Battleblock Theater, Class3, Deadlight, Dust, Hybrid, Mark of the Ninja.
- New IP/game reveals that aren't for Kinect, hopefully.
Nintendo
- Wii U! No release date or price announcements. (I'm cheating, they've already confirmed that.)
- Nintendo is going to tell us why we want to buy a Wii U. I'm talking about games I can't already get on PlayStation 3 or Xbox 360. High-def Mario and Donkey Kong. Maybe they'll have something Zelda to show, but it will be teaser artwork at most.
- Pikmin 3. (Cheating again. Already confirmed.)
- Masahiro Sakurai will give us an update on Next Super Smash Bros. Maybe a CG teaser trailer, but nothing in terms of game footage.
- Big third-party exclusive for Wii U.
- Capcom will show up on stage and apologize for Mega Man Legend 3's cancellation, blame themselves for their foolishness, open themselves to tomato tosses, and re-announce Mega Man Legends 3 for 3DS.*
- 3DS showcase: Monster Hunter Tri G, Fire Emblem: Awakening, Luigi's Mansion 2, New Super Mario Bros. 2, Paper Mario 3D, Kingdom Hearts 3D, Theatrhythm Final Fantasy, Fantasy Life, Beyond the Labyrinth, etc.
* No, they will not. This will not happen.
