What are you talking about in regards to the Canadian feeds I think that they are as good and in some cases better than the American.
Also the Canadian broadcasters at least know hockey and they can follow the play MUCH better than the American stations.
I never mentioned anything about the broadcaster's quality or knowledge so I won't argue your latter point. The PQ of the canadian SD feeds on CI have been some of the worst i've ever seen. There are some RSN that are worse, like MSG and NESN, but most are better than the canadian ones from TSN, RDS, etc.
Some CBC feeds are ok. Really, all the SD channels should look better than they do, but that's for another discussion.
The NHL Net channel is HD only on E*.
It appears that they are not showing anything different than the NHL NET Canada channel, so while the rumor is that the game schedule will be different in the US, that doesnt seem to be the case right now.
Edit: I just saw the ticker on this channel announce an HD game buffalo vs. florida 10/26. I don't see that game on the NHLN-CA schedule so they may be changing the programming soon even though they went live with the canadian version for now.
