As brought up in the NHL Talk forum, the league will talk to anyone who shows interest. That doesn't mean that they're a frontrunner city for another team. Omaha got a meeting and their metro is slightly bigger than New Orleans's without a pro sports team. Ditto Cincinnati, which is in the Blue Jackets's turf.
I predict Atlanta, Houston, Phoenix, and either Quebec City or a different American city depending on whether the NHL has an appetite to go up north or not. What that fourth city will be is anyone's guess.
