It's too early to tell for sure, but according to the press releases and info that has come out, it's likely that both types of receivers would be replaced by a whole new generation of boxes.

Of course, this deal isn't even expected to close until the second half of next year, and it would probably take a year or more after that for equipment changes to even start to take place. Of course, all that assumes that this deal gets past the SEC regulators (which it should IMHO).
