The short answer: no. The longer answer: We seem to be in the midst of a multi-year transitionary period right now. Much of this has been driven by expansion and coaching changes. Looking at where the coaching and playing talent is going, it seems the Big XII and Pac 10 will eventually come out on top, in that order.
My darkhorse call is that the Big East breaks up (or at least looks vastly different in basketball) within the next five or six years. The ACC will look the same, but the majority of its members are no longer primarily driven by basketball. So Duke is left playing basketball in a football conference.
