Why I posted over weeks ago it is easier for SEC, B1G, ACC & PAC-12 to absorb the Big-12 in the near future even if Big-12 Expands before the 2016 season.
There are Exit Fees and Buyout Notices that are required and that could take years too. Add in networks being upset and coming big time events like B1G TV income exploding per School, SEC continued success. ACC Newtork launch in 2019, and PAC-12 changing its own Network it is far easier for the Big-12 Dissolve and be absorbed into FOUR Power Conferences with their 4 Networks by 2020.
