O.K. folks, now I can call it Windows 8 officially it would seem? well my developer's preview versions just applied update #2671501 and Microsoft are now calling it "Windows 8"

This update changes the expiry date from 11 March 2012 to 15 January 2013!

I wonder why? particularly as we were expecting a public beta to be released at the back end of February 2012.

Microsoft watchers were predicting the official release in the last quarter of 2012.

The plot thickens
