I dont think the Rays front office will change their stance until someone with MLB or the Players Association pushes back.
The also have to get two ballparks planned and built, so if the drop dead date is close and only one location is making progress, they may lean that way. Montreal has no ballpark available (even for temporary purposes, Olympic Stadium is mainly why the Expos left in the first place), Tampa Bay at least has the Trop if they need somewhere for the short term.
