GOONL!NE: "Another update from Geoff Keighley on his Twitter, everyone thought that a new Zelda for the DSi was the big surprise he was referring to.
Nope, not in a million years. It'll be going down tonight and it is multiplatform."
Update 1: Also, GOONL!NE strongly now believes that it could be one of these three games.
- Call of Duty: Modern Warfare 2 - Reveal Trailer
- Assassins Creed 2 - Reveal Trailer
- Mass Effect 2 - Big fu**ing trailer
Update 2: He's just updated it saying:
"If you're at GDC you'll definitely want to attend the awards tonight at 6:30. You may be pleasantly surprised."
This is most likely where this big announcement will happen.
Update 3: "Stay tuned - GDC awards close with a surprise trailer, which will be online immediately after. And yes, Infinity Ward is here."
