I'm not sure. There are other issues as well. First, Viacom is strong-arming Dish to put their Nick GAS channel on a lower-tier of service. Meaning yet another channel for them to get revenue from, whether people want it or not.
Second, Dish wants to provide HDTV service of the networks to people whose local affiliate is not yet broadcasting in HDTV. The local affiliates, of course don't want to lose eyeballs. But Dish and people who bought HDTV want the best programming that can be offered. I know if I spent thousands on a TV, I would want to watch the Super Bowl in HDTV whether or not my local affiliate was up to snuff or not.
So there are negotiating points.
