I think the acquisition probably has to do with Gas Powered Games....Brad has been pretty chummy with Chris Taylor lately and they are working together on Demigod.
The *unsubstantiated rumor* probably comes from this. Calm down people, Frogboy is not about to sell his baby to anyone. He's a Michigander (correct terminology?) and wants to stay at home. If anything, this is a bargaining chip- a 'plan B' if you will. Worst case scenario; the bureaucratic dolts dig in their heels and Stardock moves to Redmond (the Haight-Ashbury of tech) and shares quarters with GPG.
@sethpenguin- Put down the gun, son. It's not worth it. You have your whole life ahead of you. I know that things look bleak now, but get a good night's rest and everything will look better in the morning.
