Get ready for A BIG DISAPPOINTMENT when apple gives you NADA!!! Like you haven't had that already!!!
[doublepost=1501526122][/doublepost]First I get WHY the iPad will NEVER be 4K... TOO much power to devote for a feature that a device is not really not meant for 4K... But the slap in the face is that the IPAD mini 4 has a PPI of 326... while the PRO is only 264... How is it that the PRO model is less than the MINI... No matter what you say about what pixels you CAN see...The MINI 4 is better than the PRO... Does not make sense... And the 7plus is 401 PPI.... So why exceed 264 on ANY device... All devices should be 264... And the label Retina-HD... does NOT apply to the PRO model... What kinda pro is that... At least have it come up to 326 PPI...
The iPad Pro won't go 4K any time soon in terms of pixel resolution. However, it already is capable of 4K HEVC playback in iOS 11, OS-wide. And that's what's most important.
4K is here, and Apple is going full bore into 4K as of this fall. Hell, Apple already has descriptions for movies on iTunes mentioning 4K HDR.

"In a discussion topic on the MacRumors forums, Jackson shared a screenshot of his iTunes purchase history with the 2016 film Passengers listed as "Movie (4K, HDR)" under the Type column. However, he said iTunes only let him download the movie in HD quality, which is either 720p or 1080p depending on the content."
"Another reader mentioned that the 2016 film Fantastic Beasts and Where to Find Them is also listed as 4K and HDR. MacRumors rented the film to check, and we can confirm the film indeed has "4K, HDR" next to it in our iTunes purchase history. Nevertheless, iTunes lists the movie's video quality as 720p."
Either Apple will activate 4K support in the existing Apple TV, which seems unlikely, or else Apple will release a new Apple TV in the next few months with 4K HDR support, which seems extremely likely.
In addition, Apple's QuickTime implementation of 4K HDR playback is wonderful. When I've played 4K HEVC 10-bit HDR videos (from Sony etc.) on my 8-bit non-HDR MacBook, It looks perfect. Very impressive.
BTW, for example, for a 76 Mbps 4K 10-bit HDR HEVC playback in QuickTime High Sierra, my iMac uses only 7% CPU or so. My MacBook uses about 25% CPU, which is still pretty decent, given that I can still multitask fine on that MacBook when playing back such a video.

2007-01
2010-09
2012-03 (and updated 2013-01)
2015-10
So, a new Apple TV every 2-3 years. We are right on target for a new Apple TV relatively soon.
