The movement that we saw during the Pacific shift and before is just about done. All but three or four teams are either 1.) owned by their NHL affiliate and have their long term future secured or 2.) close enough in geography and/or have a good enough relationship that they might as well be one entity.
The only NHL teams who don't fit those are the Blues, Golden Knights, Panthers, and perhaps Tampa Bay and Vancouver if you're getting picky and they all aren't changing anytime soon.
Blues were looking at teaming up with a nearby EC team, supposedly talked with Indy and KC, and convincing them to cover the incurred costs of joining the AHL (AHL franchise fee, EC exit fee, etc.) the much like the Avalanche did with the Colorado Eagles. But they're with San Antonio for at least three more years, and most certainly are looking for options close to home. They're one of the few changes to look for.
Golden Knights have their prospects with Chicago Wolves and 10 minutes away from Chicago O'Hare with cheap 3 hour non-stop flights, and have verbally expressed how much they love the arrangement. Definitely looked at nearby EC teams like Salt Lake and Idaho but both passed. Panthers have the Springfield Thunderbirds and with the AHL's office within walking distance of MassMutual Center, they are unlikely to leave.
Tampa has been occasionally linked and Vancouver has been perpetually linked with relocating their AHL teams closer by. But, the Syracuse Crunch announced in October a 12 year lease with the Onandoga County War Memorial and still have independent ownership and an excellent prospect development relationship with Tampa. Vancouver has long been rumored to relocate their team to Abbotsford, but before the new year they committed to 6 more years in Utica citing how well the city treats their prospects and were rumored to want to keep their developing stars as far away from the Vancouver media as possible.
