Can HDTV work without cable?

Yes. All over-the-air analog stations are required to convert to
digital HDTV - probably by 2009. All the NYC stations are up with some
kind of digital signal, though 9/11 stunted DTV pretty badly.

A requirement to include a DTV tuner is being phased in on new TV sets.
Any big-screen TV you buy today will support over-the-air DTV. (OK,
the stores may still have a few older sets in stock...) This
requirement will extend to smaller sets over the next year or two.
