Well, to answer your question, no they haven't decided yet.  But, to discuss
your statement, it would be very nice to have a system that could work with
varying bandwidths and resolutions.  It would mean that the same standard
could be used for broadcast television as would be used for a wider bandwidth
cable system.  It could mean that black and white programs could be shown
with sqrt(3) times the resolution of color programs, without using any
additional bandwidth, just by reallocating color information into resolution.
And, existing NTSC programs could be broadcast over the HDTV network without
using up the full channel bandwidth, since it wouldn't be needed.
