Andy Patrizio @ InternetNews.com: Publicly, Microsoft has said Windows 7, the successor operating system to the firm's much maligned Windows Vista, will not ship until early 2010, but its internal calendar has June 3, 2009 as the planned release date, InternetNews.com has learned.
Also, Microsoft will use its Professional Developer's Conference in late October as the launch platform for the first public beta of Windows 7. Microsoft plans to release the first beta on October 27, the first day of the show, when Chief Software Architect Ray Ozzie will be the keynote speaker.
