Apparently EA is tired of paying a bunch of executive level salaries, so they decided to merge BioWare and Mythic together, and in the process kicked Mythic's General Manager Mark Jacobs to the curb.  The singular team will be lead by BioWare's General Manager Ray Muzyka and the new "RPG/MMO studio group" will have BioWare's Greg Zeschuk as the "group creative officer." Mythic's chief operating officer Rob Denton will become general manager and report to Muzyka.  

At this point, effectively, Mythic is now being managed by BioWare.  It should be very interesting to see what happens with Warhammer Online now that the brains behind BioWare are at the helm.

A formal announcement will apparently be made later today, so keep your eyes peeled.
