I've just read the rumors that could confirm my thoughts: "@MacRumors: An unconfirmed source says Apple is already shooting "Shot on iPhone in 4K" ads in Iceland, South Africa, and Australia.". I think we're going to see a 4k combo in the next keynote (iphone 6s/6s plus and new Apple TV). It would be perfect, and Apple tv with apps(obviously, I'd choose this if I had to choose between apps and 4k) and future-proof. They could release a good source of 4k content now, when 4k tvs start to be affordable to many people. What do you think about it?
