There's another aspect to this discussion: Even if the various channels install and activate HD capabilities (and the providers carry them) there is still the significant quesion of the programming available in HD. Nothing sickens me more than to, for instance, watch ESPNHD with the sidebars and obvious SD content in between. Much of the programming available now and in the foreseeable future is strictly SD. There are some upconversions that look reasonable, but nothing available today can put back what wasn't recorded in the first place. Also - many "HD" channels are clearly not b'casting in HD 24/7, mostly just in prime time. And the channels that deal primarily with historical programming (e.g., Nick) may not ever install HD capabilities. Finally, tho' perhaps a different discussion is warranted, there is material that should IMO never be allocated the resources to be carried in HD (QVC, infommercials, most "talking heads", etc.)! To be sure, HD programming will increase, but how quickly? Will it catch-up to and keep up with the increasing capacity to carry it? IMO, that may also take quite a while.
Summary - programming in HD is still fairly scarce and it has a way to go to catch up with the available capacity to carry it.
