A recent issue of "Digital Audio" says that the manufacturers are working
out details of a standard which has

        Recording and playback at 48 KHz
        Playback only at 44.1 KHz (for prerecorded tapes)
        Possibly extra copy protection codes on top of the rate difference
	
So the decks will be incompatable with both CDs and prerecorded tapes.  I
think the first manufacturer to introduce a CD-compatable deck will clean
up, and the rest will be forced to follow suit or take enormous losses.
