Microsoft Games Studios announces that Halo 2 for Windows Vista now has a new release date of June 8, though the press release has a London dateline, making it possible that this announcement only covers the UK or European edition of the shooter. The Vista edition of the game was expected Tuesday, and Microsoft has once again waited until the 11th hour to announce the slip (the May 22 date was announced on May 8, the previous due date (story)). No explanation for the delay is offered.
