They are also saying that ALL channels will eventually be transmitted with MPEG4, although I can't find the quote in the press releases now.

The HR10-250 that a lot of us dropped over 1k on will be a boat anchor in a few years, it sounds like. It's exciting to see D* add all those HD channels, but it's sad to be made obsolete with something that we recently bought that I for one, thought would have a longer shelf life...
