Hi Erik,
According to Windows blog, officially they have not released Windows 7 RTM yet - http://windowsteamblog.com/blogs/windows7/archive/2009/07/13/update-on-windows-7-rtm.aspx
I am sure you are aware of this already. Windows 7 RC was made available quite a while ago - http://www.microsoft.com/windows/windows-7/download.aspx.
Regards,
