Microsoft to Make a Significant Announcement

Just noticed via Microsoft PressPass: Microsoft Executives to Make Significant Company Announcement.
They’ve got Steve Ballmer, Ray Ozzie, the SVP of the Servers and Tools Business and the SVP of Legal and Corporate Affairs (Lawyer in short terms).

They also made sure to explicitly specify this is not about the Yahoo! acquisition.
I wonder what this could be about (that’s significant)… The only reason I can think of for having a lawyer on call is if the announcement is about an acquisition or licensing. Maybe something regarding open source?

Guess we’ll all have to wait for tomorrow’s conference call to hear about it…
I will probably log on and twitter during the call…
