MTV Games parent company Viacom is currently involved in an ongoing legal battle with Harmonix. The developer accuses Viacom of avoiding the payment of performance-based bonuses, a claim that Viacom denies. We've reached out to MTV for comment.
[Update 2/7: We heard back from an MTV spokesperson, who told us, "MTV Games has ceased its publishing operations but has not been completely dissolved." Huh, wonder what that means. We'll let you know if MTV suddenly becomes more forthcoming.]
