Harmonix. All Things Digital's Peter Kafka reports that the Rock Band and Dance Central studio's re-independence cost investment group Columbus Nova $49.99.
Of course, the math gets a little tricky from there: Harmonix's buyers assumed responsibility over liabilities, including "music rights fees ... responsibility for lots of unsold games and equipment sitting on warehouse shelves." The sale will reportedly net Viacom $150 million in tax benefits -- it spent $175 million to buy the music company in the first place.
Kafka also notes the "fire sale price" can't be comforting to Harmonix employees, as he believes the studio is "likely going to be facing a very serious restructuring."
