DISH dropped MSG networks on 01 OCT 2010 (opening day for the NHL). This removed NY Rangers, NY Islanders, Buffalo Sabres and NJ Devils games as well as NY Knicks and NJ Nets games, along with misc.
college sports. They have still NOT returned MSG to the air and have no idea if they ever will.
Tonight they will drop SNY and the NY METS (oddly enough opening day in MLB), and of course they have never carried the YES network and the NY YANKEES. The Customer Service dept doesn't have a clue as to what is going on.
