and a recent blurp from Slam Wrestling: "No official statement has been released as to Kurt Angle's schedule for next week. Angle is being promoted for a September 8 match in Japan and then wrestling at TNA's No Surrender pay-per-view the next day. TNA will make the final decision, and Antonio Inoki has been in contact with TNA President Dixie Carter, about Angle coming to Japan."
They may be trying to setup a unification match with Angle & Nagata?
