After Portal 2 was delayed from a late 2010 release to a early 2011 release, many were wondering when the game would be released. According to a leak by Game Trailers TV host Geoff Keighley, it won't be that far off.
Portal 2 is the sequel to the original Portal, which was included in Valve's "The Orange Box" package of games. Through word of mouth the game became an sleeper hit and brought about a proper sequel (the original game only took a few hours for those who knew what they were doing).
According to Keighley, Portal 2 will be released on February 9, 2011 on the PC, Mac OSX, Xbox 360 and PS3, the latter of which was a surprise announcement at Sony's E3 press event.
