I got a new TV the other day. looked at 4K and asked the sales man if it was worth the extra money, even though they were doing a massive discount. Give it 5 years he said, nothing much is broadcast in 4k but the makers produce them as they do not want to be left out when other makers produce them and the must have the latest public see them. Bit like 3d. I have a mate who got one but never watches 3d, gives him a headache.
