The market made a huge flop with 3D trying to shove it down our throats for 2 years.
I am assuming this is the way the market is expecting to get back on its feet. By selling something that actually improves on the previous technology.
Its no surprised that 4K is dropping in prices relatively fast.
I would say that 4k Content will come sooner than we actually expect it, the question is when will it become affordable. Also, older movies will be reworked to sell them as 4k?
Well, we will have to wait and see.
