I think I'll just stick with regular DVDs for the time being...
Between the coming demise of analogue broadcasting (making most US tv receivers obsolete for plain vanilla over the air reception), the DVD format wars, high-definition tv...I would not be surprised to see all but a handful of deep-pocketed consumers...buy nothing at all.
Americans have become used to cheap, good, color tvs. You can still buy one--new analogue sets STILL have no warnings on them about their coming obsolescense.
When the reality sinks in of the death of analogue and the rest, I expect consumers to be angry. Very angry.
