AMD just issued a release saying that president and CEO Dirk Meyer will be making a "significant corporate announcement" tomorrow, which sounds ominously like those breakup rumors are coming true -- particularly since Dirk's on record saying that the chipmaker plans to spin off manufacturing and fabrication into a new company. We'll see in the morning -- anyone planning on throwing a blowout "last night of the old AMD" party in the meantime?

Update: The WSJ confirms it's a breakup -- but don't worry, they'll still be friends. [Thanks, aztalon]

Update 2: Official PR is here. How's "AMD and Advanced Technology Investment Company of Abu Dhabi to Create New Leading-Edge Semiconductor Manufacturing Company. Mubadala increases investment in financially-stronger AMD, which is simultaneously unlocking the value of its manufacturing assets" for an exciting title?
