I don’t understand how HDTV manufacturers make any money at all, frankly. What does a simple one go for nowadays, anyway? 300 bucks?
Even more important they are light weight.
They're probably making a minimum of 50% of the cost as pure profit ~ and once they've paid off their initial cost of capitalization for plant, equipment and design they'll be making 90% if they can keep prices constant.
The successor technology is under development as we speak and it will be even lighter, better, longer, lower, faster, cheaper and efficient. You'll probably be able to fold it up and stuff it in a coat pocket.
