It seems from what I was told that many ex Adelphia markets will be getting the new HD channels just a couple of weeks after the surrounding Comcast owned area's. So for example parts of Londonderry (ex-Adelphia customers) will see the channels after say Derry gets them as Derry was never an Adelphia market at least not in the last few years. Now how much longer will vary greatly and it can range from a day longer all the way to weeks and maybe months longer depending on the system Adelphia had in place.
