By all indications, the Big 12 is not going to implode now that Tx A&M is officially leaving. What remains to be seen if the remaining members will sign a contractual obligation to stay in the conference for a certain number of years, so expansion candidates won't have such cold feet if offered membership. The "honor system" has failed dramatically; it's time for more concrete commitments from the Big 12 membership. If the membership does sign a contractual obligation, then welcome to the Big 12, BYU.
