According to Todd Hollenshead, id Software's Rage will not be shipping in 2009. The multiplatform game (PC, Mac, PS3, Xbox 360) will be the first to use id's new graphics engine, id Tech 5.

The game, however, is expected to release before 2011. So I guess we can say that Rage is set for a 2010 release.
