[Rant On]
I for one don't buy that argument from ABC. They get more money than ESPN for their advertising. ABC have had several years now to increase their capacity to broadcast HD-Live events. ESPN has EVERYTHING available NOW in HD in parallel broadcast of ESPN and ESPN-2, and they have fewer financial resources overall than ABC. They are simply leveraging those resources much more aggresively.
I would be highly surprised if ABC's take from a typical college game is less than that pulled in by ESPN game-for-game.
The need for dual signals (which I have heard others use as an excuse) doesn't cut it with me as an alternatve form of argument. As Letterman put it, right after HD was in it's second full season, "I know the networks have the equipment, why isn't everything available in HD?"
