Size of factory? Number of employees? How many machines?
Its like saying why cant BMW produce 4 million cars from their factory instead of the 2 million they make. If LG can only make 100,000 a month initially of this screen and all 100,000 sell out within days every month, why drop the price?
Once production ramps up and the early buyers have bought then the price will drop. Same with every TV every year.
Was the same with the original 48" screen which came out at the same price and was out of stock at most places for the first few months. Once it had plentiful stock you started to see it everywhere at below £1000 and some special deals at £750.
This will go the same. Either wait or if you can't, buy now.
On your basis nobody should buy any new TV and just buy last years model if its all about the price.
Its not like monitors where they will stay at the same price (or even go up) for year and year after year. I think my current monitor they sold for 6 years before replacing it with a new model.
There will be a new version of this TV out next year, guaranteed.
