SMU Staying in C-USA?

It appears SMU is staying in C-USA with the Big 12 staying intact with 10 teams. If MWC loses Utah to Pac-10 do they add another school or just stay with current schools? If MWC added a school wouldn't it make sense to add Houston to pick up some of the Houston market. I just don't think TCU wants us in the same conference as them. I also think some of the C-USA east teams will get raided by someone in the near future.
