1Up reports on Microsoft's hopes that the release of Grand Theft Auto IV for Windows in November will revitalize (or perhaps vitalize) the Games for Windows program, which has not exactly set the world on fire since its launch two years ago. Word is the release of the PC edition of Rockstar's open-world action game will offer "a revitalized Games for Windows Live experience" with the inclusion of a separate Games for Windows client and a game marketplace. There are no further details on planned enhancements to the GFW program beyond an ability to sell games directly.
