Any place that has a dome is in the running (you need a large arena to accomidate a ever growing list of teams) but the need for decent weather is also a good indicator.
I think the top areas in the running are Atlanta (it aint broke why fix it) Houston (they did a pretty good job and I'm sure they could learn alot from their previous experience), New Orleans (they cretainly have the facilities to host such a large event).
San Antonio has a dome as well, right?
