Nothing is going to happen for a while. In my opinion there is no monetary incentive for the networks or conferences to do any realignment.
The viability of the TV agreements will be tested in the coming years. It is a pretty good bet the SEC and B1G will be able to attract the viewers necessary to justify the dollars. The question is can the networks generate the viewers and ad revenue that goes with for deals with the ACC, Big 12 and PAC 12? If they can then things remain the status quo.
The conference left out of making big money and discussions is the Big East. It is unclear that the networks will pay the kind of money for that conference as is. This is where, at some future point, you could see some realignment. Schools like Syracuse, Pittsburgh, W Virginia, and now Connecticut are at a real disadvantage. Comparing facilities of those schools against an SEC or B1G is night and day. To stay competitive they will have to hunt for a solution because the Big East isn't it. They are unable to find a 10th team.
I look for for formation of a trans-continental conference of 16 teams, four pods of four teams per pod. I would predict that it is an amalgamation of parts of the Big East and all of the Big 12. It might look something like this:
Syracuse, Connecticut, West Virginia, Pittsburgh
Cincinnati, Louisville, Iowa State, Missouri
Oklahoma, Kansas, Kansas State, Baylor
Texas, Texas A&M, Oklahoma State, Texas Tech
Rutgers and South Florida are left out of the arrangement.
