WWE announced yesterday that they will hold a combined RAW & SmackDown taping on August 20th in Columbia, South Carolina. It is likely that that this will be the final house show before SummerSlam.
The RAW house show main events have been changed from John Cena vs. Randy Orton that they were doing last week to John Cena vs. The Great Khali. Expect that main event to start early next month if not this weekend.
