Well, the SEC tried last year to push though a one + playoff thing, but it was defeated by a group lead by PAC 10 Presidents. The Pac 10 refuses to develop some kinda conference title game as well. They have Califorina and the Rose Bowl and I kinda think they don't want much to change.
It's their right to run their conference as they see fit and it's a great conference, but their actions lead to much of their own problems. imo
