Kotaku put up a live blog. They announced some other games, but nothing interesting. A lot of variations on Monster Hunter games... even a new Gundam for Vita that's some sort of hunting game. Where you battle Gundams of different scales? That's... the saddest thing in the world, to be honest.
They didn't bring Final Fantasy XIII 3. No actual Monster Hunter (guess that's sticking to Nintendo consoles for the time being). No Ground Zeroes or Metal Gear Rising. No God of War, Sly Cooper 4, no Playstation All Stars.
Just a handful of Vita games. Still some PSP stuff. And the hardware announcements. So all they talked about was Soul Sacrifice, God Eater 2, a port of the 3DS Senran Kagura game (a more pervy game than Dead or Alive Xtreme even), a years-late port of the super disappointing Muramasa: The Demon's Blade (screw you critics. Just cuz it's different doesn't mean it's awesome. What a waste of money. There's NO level design there; just empty rooms and mindless one button combat), Valhalla Knights, and a Tecmo Koei game called Touikeden.
WTF Sony? The Vita is screwed. This was a sad way to start off TGS '12. Please be better, rest of show...
