I agree with everything you said there,I am very happy with blu ray,but even tho there is little or no content for 4k in the uk as Sonys media download will only be available in the U.S ,I still would have bought Sonys 84inch 4k tv ,more than a few people have said that once you see 4k in action you will find it hard to go back to Bog standard HD ,I tend to use the dark knight rises as an example it's one of my favourite film and the IMAX scenes are amazing on my plasma.now if in a few years time it's re-released on red ray or whatever the new format is called and it boasts being much better than the blu ray I will be first in line to buy it ,but when back catalogue titles start coming out on red ray twice as good as your current blu ray the cycle just starts again,it's ok for people who buy the odd film but I've always been a big collector of movies and i want the best edition of the movie available so i hope 4k is a long way off.
