"But on the other, there are expected to be no provisions guaranteeing a highly ranked champion from a non-traditional power conference will make a top-tier bowl."
This is probably what compelled Craig Thompson to broach the possibility of an eventual eight-team playoff, and it makes me think that there will likely be lingering mistrust when the selection scheme for whatever committee is set for the new system.
I don't know that they would rush to alter the format as quickly as Thompson thinks, of course - one big unknown from the television end is what the revenue from the single semifinal round will typically be (no one really knows yet), and I am sure they'll want data on this first before they make a decision on how worth their while the reopening of the debate on expansion would be.
One thing that might concern me is that a larger playoff would slightly devalue the regular season as well as increase the potential for the very controversies that they are supposedly trying to avoid in the new system.
In an odd way, for the MWC anyway, it is rather a shame that such a system has not existed to this point, for if everything else stayed the same, they would have been able to feature Boise State a few times in the last decade in an actual playoff format. It seems to me that Thompson is talking about getting his access simply by expanding the playoffs when, given how long it took to get this far, it might be far simpler for Colarado State to just step it up.
