"Microsoft Corp's senior vice president of the Windows division, Brian Valentine, has denied suggestions that the company is readying a second release of its Windows XP desktop operating system. Following reports that Windows XP's replacement, codenamed Longhorn, had slipped to a 2005 release date, rumors have been growing that Microsoft is preparing a second edition of Windows XP for release in 2003. The speculation intensified this week with the leak of a new Windows desktop operating system build." http://www.theregister.co.uk/content/4/28212.html
Bound to happen, MS need a "new" OS every 18 months to keep Bill from starving. Be like Intel/AMD saying "OK, folks, 2GHZ is enough already".
