Yes, the official name of the next version of Windows is now “Windows 7” as announced in Mike Nash’s post on the Windows Vista Team Blog. More details are to be available at the upcoming PDC 2008 and WinHEC 2008. In both shows, a pre-beta "developer only release" is to eb shared with attendees.  Going forward, information of Windows 7 once available will be posted in the Springboard Series which is also a great resource on Windows Vista and desktop management.
