Um, first off, PS4 isn't 4k capable. Both Microsoft and Sony have been rumored to be investigating support, but neither have 4k support yet. If 4k was as close as you say, they would have both been released with 4k OOTB.
Sony talking about 4K support in the PS4:
... so it will play 4K content on the PS4. No support for 4K games, but that's different from 4K movies/video.
Are you sure that is 4k BluRay playback? Or is it just high resolution online video playback (which is certainly a step in the right direction).
Furthermore, 4k upscaling is not 4k. You can upscale to any resolution, but that doesn't make it actually that resolution. If 4k was just around the corner, you would have wide scale support for 4k natively in existing bluray players.
Upscaling to 4k is producing 4k output. Just the same as upscaling 576p or 720p to 1080p produces 1080p output. The detail might not be there as would native 4k but that's another story. The point here is that the generation of 4k video output is appearing in consumer devices. How it's produced is not important. The market is moving in the direction of 4k. Either get on the train or get left behind.
and so on. It has started and will keep coming and filtering down. Above a certain price point, it is present in all new BluRay players.
Denon AVR doing 4K pass-through and upscaling:
On nearly all products except for the cheapest:
Note that all of these Denon products were announced almost 12 months ago.
4K BluRay disc spec by end of *this* year:
Was finalised last September:
Expect all new AVR style products to be HDMI 2.0 next year if not this year. After this year, the expectation will be for everything supporting HDMI to be delivered with HDMI 2.0 support.
Sorry, but upscaling is NOT the same thing. It was NEVER the same thing with 1080p either. Either you haven't really watched many movies from actual BluRay discs, or your just making an argument for the sake of argument here. Upscaled 480p & 720p to 1080p is NOT 1080p, and neither is upscaled 1080p to 4k actually 4k. Upscaling doesn't even bring you close, especially as the scaling can be done at the wire (meaning it doesn't require nearly the processing power or bandwidth as true 4k.)
Upscaling is the stopgap measure you implement between technologies, before the new technology has hit the mainstream. It's for the early adopters who buy a $40,000 80" 4k 3D TV.
Sorry, but I still don't buy this argument. I'll happily admit if I'm wrong about the PS4 playing 4k BluRay discs, but there is no way you can convince me that the advent of 4k upscaling heralds the imminent explosion of 4k in everyone's homes, and the imminent demand for 4k video recording in every device.
None of these things have come to pass, which indicates that the beginning of broad 4k adoption is not just around the corner.
I don't think you're looking in the right place(s).
If you're announcing a new product that does video next year, it'll be old/out-dated technology before it hits the shelf if it doesn't do 4k. If Canon do a 7D Mark II this year without 4k and the successor to that is some 3 or 4 years away then its life span as a modern and relevant tool in video production will be quite short. If I were Canon and it was my xD DSLR being launched this year without HDMI 2.0 or 4K, I'd hold it off another 12 to 18 months to include it so that it has a reasonable chance of having a life expectancy of more than 12 to 18 months in the market place. But that's just me.
Heh, so I agree with Neuro here. This sounds like the successor to the "DR is everything" argument. Boy, you anti-fanboys really know how to pick em and play em. The one feature you want that you can't get on Canon, and it's immediate grounds for the doomsday arguments. Good grief. I would offer that Canon producing higher DR sensors and making that an ubiquitous feature in all their DSLRs is VASTLY more important than them suddenly putting 4k video output in all of their DSLRs "right now". And you know where I stand on the DR argument.
So yes, it really is just you (and maybe a handful of your anti-fan brothers in arms) who DEMAND that Canon jump on the bandwagon the moment it's out of the gate, before more than a handful of consumers even knows there's a race going on.
BTW, Canon has done some pretty amazing things in the past with nothing but firmware. If they can support processing full resolution 10fps RAW right off the sensor, then Canon is MORE than capable of handling a 4k pulldown. If they don't release the 7D II with 4k support right out the gate, I'd be willing to bet good money they add it later on with a firmware update. I would even be willing to bet that Canon could add new 4k features and functionality to the 1D X and 5D III as well, if the time comes that consumers really demand it. All of those sensors have more than enough resolution...the 5D III is the only one that might not have the bandwidth and processing power, but then again, with a proper pulldown, handling 4k video probably wouldn't need the kind of bandwidth as 6fps RAW (which requires about 270mb/s, with a 4:2:2 YCbCr type pulldown, you would have a 14-bit full precision luma (Y) channel, and lower precision color channels, in which case 270mb/s is probably just about right.)
Finally, if you are so dead set on having more DR and 4k video right now...I honestly don't know why your still here. There are other products out there that offer what you want. You clearly don't seem to like Canon. Even if you like their ergonomics, you put so much weight on all the things Canon doesn't have...go out there and get the functionality you want, and be done with it.
There isn't any point in all the doomsaying about Canon and the very few features they lack in their otherwise exceptionally feature-rich cameras. Canon will release that functionality when they release it. We really don't have any control over that. Not when the technology is as complex as it is...it takes too much time for new technology to be researched and developed for any customers to really have any say over what Canon does or does not include in the next camera. By the time we all start hollering for something, the next product is usually so far along in the pipeline that it's too late to change. I think it is actually smart for Canon to kind of stagger their key model releases...5D III, 1D X, 6D, then finally 7D. It spreads things out enough that by the time they start putting the finishing touches on their first 1D X II prototypes, they will be able to factor in some of their customers feedback.
