It looks like if Phoenix moves after the season (NHL on the last year of its takeover deal), the whole conference setup could be changed because some of the Western Conference teams wanting to move.
Detroit wants to go to the East but a bunch of West teams are worried that would take away their main draw of the conference and a few teams in the East don't want another powerhouse team upsetting the current balance. Columbus wants out of the West if Detroit leaves and Dallas wants out of the Pacific division if teams are allowed to move.
