I don't have a 4k tv and I think the take up will generally be quite slow. A lot of people who wanted flat screen TV's have bought them and the lack of currently available 4k content means you'd have to be very keen on it to adopt early. The result will be that there won't be a rush to produce lots of 4k content meaning that you'll have a never ending circle of low output and low take up, each perpetuating the other.

I've just gone to BT who have a 4k sport channel. I wanted the biggest capacity hard drive so I have their uhd box and it came with a list of compatible 4k tv's. What I didn't realise was that there is still no industry standard for 4k, which means that some who bought early 4k tv's and then waited patiently for content to arrive can't actually use them to access the only current linear channel. That's not going to help things along.
