Gotta agree with Scotts logic as well.
I, however, would put the best two teams in the country in the National Championship. Call me crazy. Therefore, it can only be OSU/Michigan.
Also, for me personally... I was at the KU/KSU game during the original OSU/MU game. So for me, it wouldn't be a rematch. So I would especially like to see the two best teams in the nation for the first time.
I certainly won't be outraged if it is Florida, though. They deserve it by playing a more difficult schedule... and I always thought they got hosed in that Auburn game... even though I won money on Auburn in that game.
