The third entry in the Fireteam Bravo series of PSP games was originally scheduled for a release next month, but the rest of the world wasn't quite prepared. According to a post on the PlayStation Blog, Sony's global marketing team only recently acquired new assets for the game that they will use, I am assuming, to market the game globally. Apparently the game will be sufficiently marketed by January 10th, at which point it will be released into the wild. The SOCOM team's Mark Rogers tries to make fans feel better:
I understand that this move is disappointing to some in the community, however as a result, you will be seeing a lot more of SOCOM: U.S. Navy SEALs Fireteam Bravo 3 in the following weeks! – stay tuned.
In essence, they are sorry you won't be actually playing the game, but hey - there'll be plenty of advertising and marketing available in the coming weeks to help you remember that you aren't playing it! See? Everybody wins.
