One thing to remember is that with more starters testing the market there are more jobs likely open. You see this sometimes where teams play musical chairs with their talent. I'd be surprised for instance if the Rangers opted to go with Talbot as their starter, barring him putting up some amazing season, if Lundqvist were to test free agency. Likewise with the Blues if Halak left. On the other hand, I suppose that Buffalo might have the confidence in Enroth to go with him if Miller leaves, so they may be one of those teams that are only looking for a backup.
I think there are more than the two teams that you listed that would be interested. I'd be shocked if Calgary wasn't interested in him, and not just because of the Burke connection. Florida is another.
There's a bit of a drop off after Henrik, Miller, Hiller, and Halak in the pool of goalies this summer. If he does well you could see Thomas in there, though at his age, he seems like more of a short term solution than the other four would be.
Didn't realize Halak was also a UFA, but at the same time, I'd be fairly shocked if they let both go. Perhaps they do that and go after a guy like Miller or Lundqvist, but Buffalo is definitely a team IMO that won't be adding anything, they seem to like Enroth and Hackett's a decent prospect as well. The Rangers would definitely be in the market if they lose Lundqvist, I think that goes without saying, but if they lose him, that's just another guy on the market. Calgary and Florida, I really can't see it for a couple reasons. For one, they're both rebuilding to some extent, and I can't see either team spend decent dollars on a goaltender, especially with Calgary having a few inflated contracts and Florida already talking fire sale. More importantly, though, they both have very good prospects whom they seem to want to give every chance to. Florida especially seems committed to Markstrom, and they should be, so I can't see them going after anything more than a potential platoon guy. Calgary doesn't have a guy like Markstrom, but they're very high on Berra(who I'm guessing they make room for next year) and also have Ramo. Things could change, but I don't see either as a landing spot for Hiller.
All in all, if I were to bet on it, I'd put money on Hiller being as Islander next year. There's a longer term future there, they're an organization on the rise, and he's a guy that could really help them take it to the next level. Everything else gets interesting after that, really depends on the Rangers and Blues and what they do with their pending UFA goalies. I have no idea if there's interest from BM on Miller, but it does seem like such a potential bargain bin pickup that he couldn't refuse. I'm certainly hoping for it, anyway.
