Microsoft published this page today clearly stating that Windows 7 RC will be publicly available starting May 5, 2009. As a TechNet member I have gone to my downloads page, but alas, it is not yet available. Will update this post as soon as it goes live there.
Good times…
And oh by the way; if it is made available before May on TechNet and MSDN I think that Paul Thurrott actually got it (mostly) right in his predictions…
