While the editors of Games for Windows' official magazine may not be ready to drink the Vista-flavored Kool-Aid just yet, Microsoft is ready to give Vista early adopters a handful of reasons to pick up the latest OS upgrade ... err, at least they're ready to announce a date when you may want to plan on doing the picking up: May 8th. Yup, in eight weeks, Microsoft's Games for Windows Live service (doesn't roll of the tongue as easily as Xbox Live, eh?) and its inaugural title, Halo 2, will be available for Vista users..... Joystiq has more.
