Summary from Wzor-team invite-only blog
Most likely, Windows 8 beta will be built before December 24, 2011. But only on January 13 2012 it will be known which escrow build became an official beta. Sometime between January 10 and 14, 2012 on CES 2012 it will be possible to see "some interesting device"(?) with Win 8 beta on board.
Internal conference-presentation for employees and partners on Windows 8 beta is scheduled for January 30, 2012. Members of Wzor team expect (and will actively contribute to) massive leaks of screenshots and possibly images of Win 8 Beta right after that date.
Window 8 RC most likely will be presented on MIX 2012 in April, 2012.
Internal RTM release is expected in late June-mid July 2012. First gadgets and Retail sale – October-November 2012 and official launch date is January 14, 2013.
