I agree with you, nothing will look the same in 2-5 years.
Other than that, only those who are in those meetings have any idea as to what will be occurring. That is my point. With Colorado jumping ship and the ACC stuck in a ridiculously bad TV contract, the ACC and PAC12 could join together. You don't know, I don't know.
The sad part is IMO, all of this is really going to ruin one of the best parts of college football - rivalries. The expanded playoff lessens the importance of the regular season as well. I'm no fan of the NCAA as an organization, but there could have been an adult in the room - a commissioner, if you will - who could have brought all the conferences together to maximize the value and reach of the sport as a whole instead of having what will be 32 teams on one level and another 35-40 on a second level.
