So, the pipes will magically get broader after a decade or so, or will the
attitudes of cable and satellite change?
Broadcasters have the least amount of bandwidth of the three, and they care
the most about quality and provide the highest quality of service, at least
in the U.S., but I suspect that's the case in other countries. I think it's
illogical to restrict future enhancements because there are bad actors who
won't behave the way one or more persons would prefer.

As much as I am attracted to the idea of 1080p/60 due to the shear
numbers I don't really think it makes much sense for broadcast, cable,
or satellite in the next decade or so, even with AVC. It's already been
shown those distributors all are willing to compromise HD picture
quality to save bandwidth and ad more channels.
I do seriously want faster frame rates but for the moment would be
perfectly happy to instead have a higher quality 720p/60 delivery scaled
up to 1080p or higher by the display.
Where 1080p/60 encoding might make sense in in newer video disc
technologies where they will easily have the available space. Sadly
however there is no compatible way either HD DVD or Blu-Ray can support
this under the current specs.
I'd expect the next generation of highdef discs (some new standard) to
embrace both higher frame rates and bit depths. For this cycle it is
just not going to happen but eventually folks will start making
libraries of media this good to (re)release on future media.
I don't think it will be too long before the declining storage cost of
electronic media makes it cheap to electronically 'film', process, and
store at, say, 72 FPS and then release 24 FPS movies but archive for the
future faster frame rate higher definition sales.
