Well it looks like one of the two Harmonix/Konami cases might be settling. In Harmonix Music Systems, Inc. v Konami Digital Entertainment Co, Ltd., civil action 1:09-cv-10206 (D.Mass), the parties on June 1, 2010, jointly filed a status report with the court, indicating:

Plaintiffs Harmonix Music Systems, Inc. and Viacom Inc. (collectively, the “Plaintiffs”) and Defendants Konami Digital Entertainment Co., Ltd. and Konami Digital Entertainment, Inc. (“Defendants”) respectfully inform the Court that they have executed a binding and enforceable Settlement Term Sheet. The parties are currently working to execute a formal settlement agreement. The parties thus respectfully inform the Court that they expect to be able to provide another status report in 90 days.

Looks like they have come to some agreement in this case. Still no word whether the sister case, Konami v. Harmonix, is affected or not.
