In an extensive Press Release , Microsoft announced a beta invitation for Exchange Online and Sharepoint Online in addition to a barrage of new information on Sharepoint Server 2007, the Silverlight Blueprint for Sharepoint, as well as a new flexible licensing model.

There's no doubt Microsoft is about to strike a slew of challenges this Wednesday at MIX08, among them Silverlight 2.0, IE8 Beta, and more. The stage is positively being set for some very pro-active moves from Redmond.
