I've heard of this being talked about with a few different teams, but I hadn't heard anyone was going through with it yet. I think the biggest problem they have is that you are paying simply for the name of your opponents, not necessarily how good they are.
I know that all teams aren't going to be equal (there will be teams at both ends of the cap) but we're supposed to believe that they all have the same chance at being successful. There's also the fact that we don't even know what any of the teams could end up looking like.
After this season, I think it might start to help, but it could really get messy if halfway through the season they're charging twice as much for the worst teams as they are for the guys heading to the playoffs. Hopefully they'll stick it out for a couple years to see how it works once things settle down.
Hockey in HD is one of those things people used to claim would help get more people in the sport. I think it helps just to have the 16 x 9 screen, to allow more coverage of play on the ice, let alone the clarity of the picture.
