Windows 8 Preview expected at WPC, Beta coming next

A pre-beta build is expected to be previewed during the ongoing WPC 2011 according to various sources.

Microsoft is also said to start on the beta build ready by BUILD conference in September as soon as the WPC concludes. So hopefully we will see a build with the new Metro UI during the WPC, a beta build during the build conference and the RTM build by April 2012 if everything goes according to plan.
