The ACC is now stable at 14 (football). No need to expand.
The B1G is now stable at 14. No need to expand.
The SEC is stable at 14. No need to expand
The PAC 12 is stable at 12. No expansion here.
The Big 12 has only 10, and West Virginia could sure use some geographic support. It is certainly possible although I think unlikely, that the Big 12 picks up 1 or 2 more. The most likely are Cincy and/or UConn. In fact, those are the only two that seem likely for any BCS expansion, and even then, UConn is iffy.
The AAC is stable at 12 if UConn and Cincy stay.
The MAC is stable at 13 or could add 1. Would likely stay at 12 if UMass leaves.
The MWC is stable at 10.
CUSA is stable at 14.
Edit: The SBC will have 11 football members. It likely will add a 12th from the ranks of the FCS.
IMHO
I think we are almost done with realignment.
The Big 12 stays at 10; by order of UTexas
The only near-future movement could be an add to the MAC from CUSA or the SBC; or the MAC could add JMU or Delaware instead.
If the 12m revenue cap is enacted, only the SBC makes any moves at all, and that would be one additional (to 12 football) from the FCS.
We're done.
