Don’t look for WWE to challenge CTAM to a rematch at this week’s Summit. Last year, WWE planned for a few wrestling stars to attend Summit in Philly to learn strategies for promoting SVOD service WWE 24/7. But CTAM pulled the plug, saying their presence would be disruptive. So, we were hardly surprised to hear WWE superstars Sgt Slaughter and Staci Keibler opted to let their CTAM membership expire this year. Keibler, following her "Dancing with the Stars" stint, has moved on to other opportunities beyond the ring. And Sarge has different motives for Beantown. He’ll be in Boston next month slamming heads at WWE’s annual PPV event "SummerSlam," as Comcast launches WWE 24/7 locally and nationwide.
