Announced this year?
Guild Wars 2, Star Wars: The Old Republic, and Diablo III. Yeah, we all know they exist, but all three are taking the "when it's done" approach. I'd like to be able to get all three this year. Oh yeah, and MechWarrior 5.
New stuff announced, hm? ok...
A new IP from Double Fine, maybe a new take on Arthurian legend.
Mutant League Football 2012.
Megaman X-9.
A new IP from Blizzard, perhaps in the puzzle/adventure genre.
Final Fantasy Tactics 2 or A3. It's a fantastic series that deserves some love.
A new IP from Team Sonic that *gasp* does NOT involve the Hedgehog or his world.
-(I don't expect it to be good, just to see if they CAN do something else.)
Robot Unicorn Attack 3DS. (or maybe an adultswim games compilation). I think that would be funny.
A real 3D Pokemon RPG on the Wii or Wii2. Battle Revolution sucked.
Grand Theft Horse 2. (heh.)
Knights of the Old Republic: Revan's Story: The Game. Sorry Bioware, TOR and a book aren't good enough.
Call of Duty: Revolution. A semi-historical shooter that lets you play through some significant conflicts in history BEFORE World War 1.
A new dogfighting IP. I mean aerial combat, not animal torture. Would be awesome as an MMO.
Legend of Dragoon: Subtitle. I don't really want to call it a "2", but the game deserves a series.
I know that's too many, but none of those will probably ever exist so... screw it.
