There is little to no impetus for existing BCS conferences to expand.

The reason given by conference expansion proponents is "to have leagues of 12 teams so they can hold a conference championship game"; unfortunately for schools like us and Utah, the tide of popular opinion has shifted on Conference Championship games, and the leagues that currently hold them are at best ambivalent about them, and some wish they didn't have them at all. Ironically, it is the SEC--the conference that started this fad in the first place--that has been most vocal about how much they dislike their Championship game.

The popular opinion is that Conf Championships are a hardship for good teams to get to BCS games and particularly the BCS Championship game, and the added revenue from the Championship game is not seen as sufficient to make up for the added risk of holding the game in the first place.

The last time that expansion happened with the ACC gutting the Big (L)East, it wasn't Conference Championship games that where the main cause (although they took the cash while they were about it), but TV contracts.

The ACC was the weakest of the BCS conferences in football prior to expansion, and with the U.S. in a recession when the next round of TV contract talks were scheduled to begin, they knew they would be in a very tough spot at the negotiating table.

Plus, there were rumors that other conferences might come after Florida St to try and make themselves look more attractive to ESPN, et.al., so the ACC took the breathtakingly audacious step of calling Ernie Tranghese's bluff and stealing his best teams from the Big East.

This boldness was rewarded the next year when the ACC got a large raise in their ESPN TV contract, including the (now) plum Thursday night time slot.

If there was going to be a chain reaction of expansion and changes, that was the time it would have happened. Instead, the only other changes were the Big East inviting a couple of schools in desperation, and that, as they say, was that.

Once again, in the current climate, there is little to no impetus for conferences to realign or expand, and until something comes up (perhaps the NEXT round of TV contracts?), there won't be any changes on the college football map.
