Here is my prediction:
Rutgers/UConn go to ACC
WVU/A&M go to SEC
UT/TT/OU/OSU go to PAC
5 Big 12 teams remain and don't dissolve conference and negotiate exit fees equal to television money of other 5 (tier I and II)
4 remaining Big East schools (USF, Cinn, Louisville, TCU) join Big 12.
Big 12 adds
1. BYU - obvious choice although they may be a geographic outlier.
2. UCF - additional school in Florida to establish Florida recruiting. 40k+ fans is one of top 5 for non-AQ schools.
3. ECU - after BYU has most fans of any non-AQ school at 50k per game.

While that sounds ok to me... Im sure Mizzou would be begging for SEC
