A couple of things to note about CI, HD and the RSNs.
First is that Fox Sports (including Fox Network, all FSNs and RSNs that use the Fox broadcast facility) only has the capability to broadcast a dozen or so HD games at once. That is all events, etc. Next year all the FSNs will go HD full time, so then it should not be an issue. Quite often the reason a game is not in HD (HD in general, not in HD on CI) is that other games outrank it. Prime reason why my beloved Kings are only broadcasting 10 games in HD this season. RSNs like NESN or CSN are not part of Fox and thus tend to broadcast many more games in HD.
Second, just because it is available on the RSN-HD channel doesn't necessarily mean it will be available on CIHD. From what I've been told there are two forces at work. First is that Dish has to pay extra for the HD games on Center Ice, so they don't always have them because they want to keep their prices low?!?!? (I don't buy this one btw). Second is that in order for the game to be in HD, it has to be up on both the 129 and 61.5 satellites, so all customers could see it. This makes the most sense as there would be a lot of customers pissed that it is listed as being in HD on the CI schedule, but couldn't get it because it is only on one satellite.
Third, keep in mind that directv will list games in HD that are not actually in HD. Just because they are available on the HD channel, doesn't equal HD. I loosely kept track through the latter part of last season, and in general, 1-2 games a night that were listed in HD were not actually in HD. Overall, Directv had about 50% more games in HD than dish. I'll be keeping track this season of it in helping me decide to stick with Dish or switch to Directv next summer when I move. It could be worse, last season cable had an average of 1.2 games per week in HD (although twice they did have HNIC in HD!). Supposedly this season they will have 1 game a night in HD on cable.
btw - in case you couldn't tell, I'm glad the season is finally upon us!!!
