Exactly. Canon DSLRs not having 4k video has precisely nothing to do with Digic. It's simply locked out/not added in. We got 14FPS from dual Digic 5 at 18mp (with a dedicated Digic 4 just for AF). And now, Dual Digic 6 is soon to give us 5FPS at 50MP (and handle AF as well). So one single Digic 6 chip should be able to give us perhaps 6-7FPS at 25MP. If Canon really wants to go over 8FPS in a 5 body, then maybe we get a Digic 7 to do it. BUT, given the fact it seems as though the new 1DX2 will "maintain the same FPS as previous model" (from prior CR post), I don't suspect they will push the envelope on the 5 body much higher if any than it is now.

I see. So...the EOS 1D C, with dual Digic 5+ and 4K video capture is...not made by Canon? ...not a dSLR? Or is dilbert just flat out wrong...again?

Why should we care if a camera has digit 4, 5 , 6, or 7?
I am no expert but generally as microprocessors advance the process lithography is smaller which has several consequences.
Firstly silicon wafers have a defined surface area, so the more processors one can get on a wafer the cheaper the end product. That's nice even if it doesn't mean we'll see lower prices.
But smaller chips (smaller because the process is smaller even though more circuitry is more involved) require less power so the potential for longer battery life is there.
Smaller process can yield faster clock speed cpu's at the same wattage
so more stuff can be done and of course the more processing that can be done while images are being captured the better the image can be. Higher iso images tend to have larger file sizes than the same image at a lower iso, so higher iso imaging becomes possible, and lag times writing could go down.
So I'd say that that all other things being equal I'd want a camera with the latest digic. I'm waiting for the time when photoshop runs on camera......

All good stuff. But if all I'm doing is surfing the internet and posting cat pictures (Don Haines) I don't need a 6 core Xeon processor (a la MacPro). It's faster. It's way cool. But isn't really giving me anything more than an i3 or i5 for what I'm doing. Point being is that I suspect a Digic 6 chip (or perhaps a 6+) will do everything thus far rumored about a 5D4, and therefore no need to put a new Digic 7 chip in it. But, on a 1DX2, I think it's safe to assume that Dual Digic 7 chips would show up, as a 20MP 10FPS crop body 7D2 is already using dual Digic 6, and probably not quite to their limits. I suspect one is enough to get 6FPS at 25MP

PLEASE use the same body as the 5D Mark III!!
I just purchased an Aquatica underwater housing for my Mark III (I couldn't wait any longer) and if it works with my housing, I'll be first in line to buy the Mark IV.
You did that with the 5DS, so here's hoping!

Hardware encoding in Digic 6 is limited to H.264 1080p60 maximum. That series of processors uses mp4 files at 35 mbps as its native format. To do anything better you need to do it in software, which is why more advanced Canon cameras often use two or more processors. They have to otherwise the processors could not handle the computing demands. Whenever you see dual (or more) processors in a camera the reason is that the tech available to the engineers is not up to the task. Those cameras probably have additional dedicated hardware included as well to assist in that, so it is technically an inefficient solution to the engineering problem. To shoot 4K efficiently with a single processor you will need a Digic 7/Digic DV5 processor. The DV5 is already here, so it is reasonable to presume that the corresponding Digic 7 won't be far off.
IMO 4K footage won't appear in Canon consumer cameras until the Digic 7 processors are included, so if the 5D4 comes with something like dual Digic 6 processors it is going to be crippled from the get go. It would be a camera built for the past, not for the future. Given the option of using dual Digic 6 processors or waiting a bit longer to use Digic 7 processors, the smart thing for Canon to do is wait. Otherwise they will have locked one of their flagship products for the next few years into obsolete tech, much like they did unwisely with the 7D2.

The 5D3 already has Dual Card Slots.
Nooo! Please not. No one really need a popup flash with a lousy Light directly on the cam... but maybe a build-in radio trigger coold satisfy a lot of people. I would like to see some new engineered stuff on the Viewfinder. Damn, the time is right to make a hybrid optical Viewer with elektronic information on it. Make a Zebra, a global shutter and get rid of that picture bridge.
Take back the A-Dep function and maybe the Eyecontrolled focus... and for the DR Freaks, make +2EV more Range

Don't think of a pop up flash as a flash, but as an optical flash commander. Now does that sound better?

I do - all the time. When I'm on travel, and running around doing a million different things, setting up off camera flashes is simply not an option. So I need an on-camera flash. A 580EX is so large that it displaces a lens. So I carry a little tiny Sunpac to replace the missing pop up. It's a pain, it's fragile, and it's not ready to use when I need it in all cases. The pop up is often just the blip of fill I need and it's way better that the alternative which is nothing at all or a POS little on-camera flash.

I want:
More DR: it doesn't even have to be 14+, just give me a bit more than every other Canon camera released over the past 5 years.
4k video: H.265 would be nice...there's already a Samsung mirroless cam with this capability
RAW 1080p @ 60fps: or at least a VASTLY better compressed 1080p codec, make it look as good as the jpeg's
Dual Pixel AF: would be so great for video focusing!
What we'll get:
Better high ISO jpeg performance, marginally better high ISO RAW performance
1fps shooting speed increase
An extra button or two
Strobing light correction
built-in intervolometer (FINALLY)
"IV" badge
I actually think that the new 5D might get Dual-Pixel AF...about 50/50 chance. Just trying not to get my precious little hopes up. :'(
