No one is saying its going to happen next year or even in five years, the ACC GOR is what is slowing the whole process down. Once those schools are free from their GOR's, then everything will fall into place for this new league to be formed.
The question today is what is going to happen to the Pac 12, are they going to try to patch things up or are other teams like the 4 corner schools going to leave. ND is going to remain independent for now, how long that lasts, no one can say.
For the next 5 to 7 years the SEC and B10 is going to be making money hand over fist, and the ACC, B12, and P12 schools will try to survive. All hell is going to break loose when the ACC contract is up, and those schools are tired of making little money when they could double or triple their income, that is when all hell will break loose.
