"After months of speculation, Microsoft plans to give developers their first hard look at the next version of Windows in October. The Redmond, Wash., company expects to release a 'developers preview' of the new operating system, code-named Longhorn, at its professional developers conference in Los Angeles," reports CNET. Also, WinInfo has some early screen shots.
Comment: don't get excited: Longhorn is probably at least three years away from shipping.
