The bomb of confusion that manufacturers aren't quite ready to drop
yet are the High Definition formats, and most certainly they are on
the way. The software side (movies) is very worried about releasing
material with a serious advance in quality for a whole host of
reasons. The hardware people know they are dead if they don't get
mainstream sell through on HD and that means plenty of software
coming soon.

HD TV can be stunning, but right now there is so little to watch, and
almost nothing entertaining. OTOH I could see it easily becoming the
hugely popular home movie format, ala 8mm chemical cameras of the 50s.
