Canon 5D Mark IV (forecast)
NEW: Canon 5DS Review.
There is no Canon 5D Mark IV, and probably never will be.
Canon usually lays off the "Mark" sequence after about Mark III for anything, and with the introduction of the 5DS in January 2015, there will probably never be a 5D Mark IV — although if I die before it comes out and can't update this page, this will be the link to order it from Adorama.
If there is a Mark IV, it should be a higher-speed, lower resolution variant of the 5DS, figuring about 10 FPS and about 22 MP.
I doubt Canon would bother with this. Yes, a fast consumer full-frame camera for sports and action it seems like a nice idea, however the smaller format of the 7D Mark II makes more sense for consumer sports shooting, and for pro use, the 1DX is still king. The world of actual shooting (as opposed to desk jockeys reading about cameras on the internet) doesn't really need a fast consumer full frame camera.
Specifications (target) top
61 cross points.
All Canon EOS EF lenses made since the 1980s work perfectly.
The only Canon lenses that don't work are the old manual focus FD lenses and earlier.

EOS iSA System for 252-zone (18 x 14) Evaluative, as well as 6% central and 1.3% spot metering as read from that 150,000 pixel sensor.
Paradoxically, spot metering is only from the center sensor; AF-point linked spot metering isn't there.
Can read light flicker and the camera can be set to offset its shutter delay to optimize color and exposure under flickering sports arena lighting.

Either of the LP-E6N (new, included) or the old LP-E6 batteries work. The new one has more capacity than the older LP-E6 battery, and they are interchangeable and both charge in the usual Canon LC-E6 charger.

$3,799, October 2015, but only if actually introduced, which I doubt.
17 October 2015, but I doubt it will ever be introduced.
Late November 2015, but I doubt it will ever be introduced.
The 5D Mark IV will probably never be introduced. Instead, Canon called the 5D Mark III replacement the 5DS, and we're done. Canon rarely carries any Mark series past Mark III, so I doubt there will ever be a Mark IV. We don't need a high speed version of the 5DS; if you do, it's called the 7D Mark II (for consumers) or the 1DX (for pros).
For a shoot today, buy the 5D Mark III and never look back. There is always something new coming that we can't get today. If you have photos to make today, you can't make them with a camera you can't get.
There's always some next great thing that we can't buy today, so forget about the Canon 5D Mark IV until it really becomes available.
Even the 5DS doesn't exist. Sure, Canon has announced it, but since it won't be shipping for months, that means that Canon still hasn't worked out all the bugs.
Even if announced today, it will be many months more before anyone gets one.
Any idiot can count to four, but in this case, there won't be a 5D Mark IV because it's called the 5DS.
