Wzor is claiming that the final sign off is set for July 13th. According to a translation, this is the final roadmap for Windows 7:

FINAL ROADMAP FOR WINDOWS 7 [CLIENT-SERVER]:
6/1 - 6/19 BUILDING RTM ESCROW - already assembled RTM ESCROW.
6/22 - 7/10 RTM RECALL - assembly and search for candidates to the final RTM release.
7/10 WINDOWS 7 RTM FINAL BUILD TARGET - build day "gold code".
7/13 WINDOWS 7 RTM SIGN-OFF - the date of signing the final RTM release!

We previously reported that Windows 7 could RTM at the end of this month, but if Wzor is correct. and that's a big if, it looks like we may now have a final RTM date. Wzor is stating that the latest RTM branch build is 6.1.7263.0.win7_rtm.090619-1900, and the latest build in the winmain branch is 6.1.7233.0.winmain.090614-1655, and that the next winmain assembly will be the final RTM build.

We're still waiting on pricing information for Windows 7, and the final release date is still set for October 22 [via neowin].
