and many more but cant think

The only definite one I can think of off the top of my head in 2008 is Gears of War 2 (Left4Dead is 2009 correct?).

Other than that, Fallout 3 is a big maybe (it was a definite until the E3 showings), Madden is a maybe, LBP is a maybe, and Fable II is still a maybe.

Wii:

• deBlob
• SPRay
• COD:WaW
• Tales of Synphonia 2
  
• GHWT (Wii version because I can bring it to people's houses)

Xbox 360:

• Infinite Undiscovery
• Fable II
• Deadspace
• Last Remnant
• bunch of used games

Not sure which console:

• Ghostbusters
• Force Unleashed
• Prince of Persia (PC or 360)

PC:

• Fallout 3

PS3:
Resistance 2
LittleBigPlanet
Motorstorm: Pacific Rift
Bioshock
R&C: Quest for Booty
PSP:
SW Battlefront: Rouge Squadron
Secret Agent Clank
Crisis Core: Final Fantasy VII

Wii-
MP3 (yea I have been putting it off)
The Conduit (if it turns out to be good)
Animal Crossing

ToS 2

Star Wars: FU

Sonic Unleased... (50/50 shot here)

PS3-
Madden 09
FarCry 2
Restinance 2 (if it lives up to expt)

I will most likely buy a few more, but these are the one I am considering for now.

I'm not impressed by Nintendo or Sony's lineup this year. For some reason 360 has a ton of great games, which I will (mostly) buy later while I get old stuff I want :D
