We're creating eight eight-team conferences. I read today that one of the Pac 10 officials said that they will not have a conference championship game and instead push for two BCS berths, one for each division champion. Assuming the Big Ten does the same thing, (and the SEC and ACC/Big East superconferences do too) the BCS games will be between all the division champions, and any at-large teams are left out.
This happening could be the scenario that forces Notre Dame into a conference, so they can potentially get into the BCS games.
It also sets up well for a potential 8-team playoff.
