Yes, this is already being discussed
here.
In short, the Rose Bowl is obligated to pick a BCS at-large team if Oregon makes it to the title game. Since it doesn't appear that any other Pac-12 teams will hit at-large status in the BCS, then (an undefeated) Notre Dame, the loser of the SEC Title Game, Oklahoma, and LSU are all potential at-large candidates.
If Notre Dame loses, though, I don't see them making the Top 8 and getting a BCS berth. They become a simple 'at-large' if they fall out of the Top 8 of the BCS, and there are more enticing matchups against Nebraska the Rose Bowl could make.
Frankly, if Notre Dame loses one of their remaining games and Oklahoma wins out, I'd put money on the Rose Bowl picking Oklahoma. Much better matchup than any of the other at-large candidates, save for possibly LSU.
