InfoWorldMike writes "Before Vista is even out of the gates, a Microsoft exec was talking Wednesday about Windows' replacement at a VC conference. Speaking at The Venture Forum conference, Microsoft's Bryan Barnett, a program manager for external research programs in the Microsoft Research group, said multicore architectures are of particular interest when weighing what to put in future operating systems at the company. "Taking full advantage of the processing power that those multicore architectures potentially make available requires operating systems and development tools that don't exist largely today," Barnett said. Well, with Vista in the pipeline as long as it has been, you must admit it is not surprising Microsoft is taking the long-term view. And it won't be built overnight: There is no timetable for a Windows successor right now. But early work on this effort has not yet been organized, with five or six small projects afoot in various places throughout the company, Barnett said."
