I don't know from my uninformed outsider's perspective. But I always start from a stance of skepticism, assuming that folks are just putting bargaining chips on the table for leverage in negotiations. Sure, sometimes they are very real... but usually it seems not at all. Remember when the Cubs were talking about moving to the suburbs not too long ago (was it Rosemont?)... sure thing! All while negotiating a plan for upgrades for Wrigley.
