I honestly don't see ASU being let into a conference until their arena situation is figured out. I do think that had a lot to do with the failed bid into the NCHC.
As for conference stability, other than the Alaska schools, I think the other schools are pretty stable, even if they some are on shoestring budgets. That being said, I've heard a few coaches talk over the last few years of another realignment, something that is a little bit more planned than what happened when PSU game onto the scene & everyone had to scramble. What I'm hoping that means is that some form of the former CCHA comes back, with teams like Robert Morris or Niagra joining it, the NCHC dissolving & reforming as the WCHA. (If this were to come, I would hope Miami-Ohio & WMU rejoin the CCHA clone, with MTU, MSU, Bemidji joining the WCHA.) - Other than hearing rumors, everything else is just my thoughts on it.
