Here is what I expect to happen:
Texas: Hey Big 12 losers, we could make $X more by moving to the B10. We'll stay with you guys, which is the only way the B12 will be distinguishable from the Mountain West, but we want a larger share of the B12 revenues.
Rest of B12: Thank you sir, may we have another? Sorry, Baylor, KSU and ISU, but you guys need to fork over your share to Texas.
Baylor, KSU and ISU: Thank you sirs, may we have another? Please don't banish us to the WAC!
