Electronic Arts' GDC game lineup
Among other things, EA is bringing some pretty big guns to GDC in March. They'll be speaking about Sims on the Wii, seeking new IPs and other stuff. Aside from those, though, the following are listed as confirmed to show up:
Crysis
Hellgate: London
Mercenaries 2: World in Flames
The Orange Box (this has Half-Life 2: Episode 2, Portal and Team Fortress 2 in it)
Oh, did we mention? These won't be on the show floor. Seems they're only for super-secret, special people. Oh well. We're sure stuff will get leaked about them no matter who is or isn't allowed.
