Viacom and Harmonix have been passing the bill back and forth to one another like a ping-pong ball. The latest update is that Viacom has been ordered by an arbitrator to pay former Harmonix shareholders $383 million.

The dispute is all over promised bonuses that were only partially delivered when Viacom acquired Harmonix, and then consequently sold them off.

Viacom is not accepting the decision without a fight and has filed suit under the premise that arguments and evidence were "improperly excluded."
