I would not count on Cox adding anything. I have been asking them for info on adding more HD content for a few years now. Thier answer is always the same: We hope to have more channels by the end of *whichever season it currently is* We have to work out the contract with each channel locally. Cox has offered to carry the HD signals for all local channels, however they have denied our request..blah blah blah.
When I asked some of the local channels this (WAVY, Fox43, and WVEC, they tell me that thier signal in HD is available to Cox, but Cox refuses to compensate them for it, when Cox charges us to see it (they say HD is free, but why do I have to subscribe to thier digital package which really isn't digital, but that's another topic). Cox wants to charge us for the locals, but not pay anything for it. It is kind of like in Happy Gilmore when the old folks are making the quilts and get nothing in return for it, while the home makes the money from it, and you feel good about buying them because you think that you are giving to the home.....
