In what is sadly becoming a common trend, The Orange Box is the latest game to see a release date slip on the PS3, while the 360 (and PC) version remains on schedule.
Valve's game is being ported by EA to the PlayStation 3, which might explain the delay after their whining about how hard it is to code on the PS3.
Valve's Doug Lombardi said the delay will be "a couple weeks." True gamers are getting Orange Box for the PC, anyway.
