too expensive?

I think that HDTV will take a while to become main stream because of the upgrading costs to broadcasters and the expence of the sets to consumers....

Agree. And the official standard is being challenged by broadcasters right now, as it practically doesn't transmit. Very low coverage due to signal characteristics.

Existing standard would put broadcasters (as opposed to cable and satellite) OUT OF BUSINESS.

They are succeeding in their appeal.
