It will not take half a year or more to rearrange the channels on 110 and 119, probably not even a month or a week, especially considering whats at stake, for them to get a competitive edge against DirecTv before they launch the locals, just as me and a guest mentioned earlier in this thread. They would probably put a lot of the channels that they are going to move to 61.5/148 instead of 105/121 because it would be stupid to require people to have to put up a SuperDish to get those extra channels instead of an 18" dish that is a lot cheaper, smaller, easier to install, and the fact that there is probably a bit of space at the wing slots for those channels. Dish should have decided to do this a few months ago when they first found out about DirecTv's satellite delay.
They are still only planning around 100 cities by the end of the year, just fighting the issue with some states not being able to get the locals. Once they launch the new satellite next year then it should not be an issue to get the SuperDish to receive a signal in those areas that cannot receive a signal right now.
