Pac-10 administrators arrived in San Francisco this weekend to a report that the conference was ready to invite Texas, Texas A&M, Texas Tech, Oklahoma, Oklahoma State and Baylor from the Big 12 to create a 16-team megaconference. There has also been a report that Baylor could replace Colorado in that scenario or the Pac-10 could choose to keep the status quo or add only two teams in a smaller move.
I think the Big12, SEC, and Big10 will figure this out and it won't be as radical as formations of 16 team conferences.
As for the PAC-10, leave it the hell alone. I'll totally against adding any teams east of the rockies to a division where most of the schools are a stones throw from the pacific ocean.
