If the ACC and Pac-12 both go to sixteen and the Big East dissolves, we will be fine. Suddenly there will be a bunch of Big East bowl tie-ins available and the 4 biggest conferences are going to be like Hungry, Hungry Hippoes trying to gobble them up. Do you really think the Big Ten and SEC are going to be ok with the ACC and Pac-16 having a bigger mouth than they do?
West Virginia seems like a lock to the SEC. Mizzou will get wooed by the SEC and Big Ten. Notre Dame and BYU are going to have to do some soul-searching about whether or not there is really still a place for independents in the BCS.
I think we will see WVU, Mizzou, and one of TCU/Baylor/Louisville go to the SEC. I think we will see Notre Dame, Iowa State, Kansas, and Kansas State to the Big Ten.
I think we will see South Florida, Cincinnatti, and two of TCU/Baylor/Louisville go to C-USA and we will watch them to develop into a fringe BCS conference in a few years. I think there's a good chance BYU rejoins the Mountain West.
I think there's less of chance but still the possibility the following happen: MWC and WAC re-merge to sixteen teams minus the Texas schools making the jump to FBS. Army and Navy join the MAC along with a northeast school jumping up to FBS (possibly Villanova?). I could also see the Sunbelt finding enough southern FCS schools willing to go FBS to fill out a sixteen team league as well.
