I was surfering round looking at the typical rumours sites and found a link to the german web site http://www.winfuture.de/web/index.php?inhalt=run/news/news.showem.php&ID=9786 which reports that Yukon is now available for testers and shows screenshots from the associated readiness kit as well as allowing you to view the readme document.

It is amazing how people seem to ignore NDA in order to post "exclusives". Also shows what a leaky world we live and how fast information travels.

I am not on the beta but I am very much looking forward to seeing Yukon.
