"Through our sources close to Microsoft, we can now confirm that the Windows 7 RTM build that will be chosen over the next few days will be officially announced on July 13th, 2009, the same day as the WPC09 (Worldwide Partner Conference) will take place in New Orleans.

As I just mentioned, Microsoft is still in the process of testing and choosing from the RTM candidate builds as they need to ensure that all show-stopper bugs present in the OS have been eradicated to ensure as much of a smooth, bug-free release as possible. TechNet, MSDN, and other partner connections will be getting their hands on the RTM build shortly after, if not on the same day."
