The problem is that unless every customer has an MPEG-4 capable set-top-box, both an MPEG-2 AND MPEG-4 signal would have to be sent out. That is certainly not going to happen any time soon.

Wouldn't switched digital video take care of that problem since signals are only sent "on-demand" so to speak?
Sure, but at this time that option would would still require expensive equipment upgrades. I don't think a firmware update to our current set-top-boxes would be enough. I remember there being some confusion about FiOS being a mini switched video system at the customers ONT when it first came out, but those rumors have been put to rest as FiOS went with a more traditional cable TV delivery solution so as to make use of relatively inexpensive and widely available equipment.
This is just stuff that I have read about here and there. I am no expert on this topic. Don't take any of this as gospel.
