I think in most cases, the first round games will be fairly expensive for tickets through second parties, like $200-500 depending. But imagine say Cincinnati is a host team, they would not play at home, they'd move the game to the Cincy NFL venue, same with Wake Forest and Duke and Georgia Tech and several others.
The weather situation could get interesting, we could see Miami (FL) playing AT Wisconsin, in December, or even worse, in ORLANDO.
