Scoble mentions an important MS Office announcement is being made tonight at 9:01pm. I have a pretty good feeling what this is but check out http://channel9.msdn.com/ShowPost.aspx?PostID=73329 to find out for yourself- 9:01pm (Pacific) or later.

Update: Office 12 to use standard XML as file format, publish specs for royalty free use. Get ready for .docx, .pptx, .xlsx, and more.  Mary Jo Foley has her report here. More details available on June 6th at http://www.microsoft.com/office/preview
