That is definitely a concern for me being a Bulls and Cubs fan - CSN is on every day there is a game. After seeing what happened to CSN NE, it wouldn't surprise me to see them all dropped. But at the same time, I look at CSN Chicago, and since they have the Bears Pre and Post Game shows, over half of the White Soz, Bulls, Cubs, and Blackhawks, there seems to be a lot of value in CSN Chicago. Plus isn't CSN Chicago considered a base RSN in almost all of Illinois, Indiana, and Iowa, and aren't the Cubs/Sox available to watch in all those states? I know the Bulls/Blackhawks are blacked out in certain areas but baseball seems to be available more widely. So to me, CSN Chicago has a lot of value due to more professional sports teams on the single RSN to more people. I don't know the other RSN's as well, maybe there is another RSN that has that much content that was dropped.
I don't know how much the other RSN's reach in terms of number of people, but I am guessing that these RSN's are an all or nothing proposition. Would Comcast want Dish to drop them or would they prefer they stay on? I don't know the business model or the legal side of things, but couldn't Comcast want Dish (and other future providers as contracts run out) to not pick it up so that those die-hard people would have to get Comcast TV? Or are the number of eyeballs more important to them from an advertising revenue side of things?
