My crystal ball is not clear enough to determine whether some of these
"extra bits" will be available for audio or not.

It is my rather biased opinion that as additional revenue-generating
opportunities become available using data tunneling via HD Radio, stations
will be making thoughtful decisions to balance audio and data content.

With reference to the receivers, I understand that the current crop of
multicast receivers support "flexible" bandwidth allocation.
