Following an announced delay back in January, it looks like the PS3 version of Ghost Recon: Advanced Warfighter 2 is being moved again from June to a (tentative) August release. The Xbox 360 version of GRAW 2 released in March. No explanation is given for the delay.
It's no secret now that Ubisoft has not been happy with the PS3's sales. The delay doesn't mean they are adding extra content -- although given the extra time sitting around it'd be nice. All PS3 owners can do now is hope this game does eventually come out and, with any luck, won't just be canceled like the PS3 version of THQ's Saints Row.
