Awesome! I guess the three people in the UK with 4K televisions are totally stoked for this.
Unless people start sitting two feet from their TVs or start buying 240" TVs, 4K is a completely useless marketing scam. 4K might be noticeable for some people in some desktop monitor applications, but it is just ridiculous in TV applications.
Not sure why people are downvoting you. You are exactly right. 4K is a COMPLETE waste of time in most normal settings. Stick with 1080P and save the money unless you're sat a couple of feet away or your telly is the size of a bus.
