In Oriole territory, they have been moved from Comcast Sports Net to Mid-Atlantic Sports Net (which is owned by the O's owner). Guess what!?! MASN doesn't have an HDTV channel.
So even if Dish does pick up Comcast Sport Net's HD channel, there really won't be much on there this summer except a few MLS games and I guess the last few months of Hockey/Basket ball.
So in the Balt/DC area, RSNs are not nearly has exciting as they were at begining of the fall/winter sports season.
