The 1DX only uses the DIGIC IV chip when you set it to the AF mode that uses color info from the RGB metering system, so as I said, the same AF other than for that mode.
(although I guess since the mirror black out and fps are different they might have to tune a few parameters a touch differently, I don't know if the slower fps and longer blackout cancel out and make it like the 1DX or not quite; I guess they might have to retweak a few things for the 5D3 version and, potentially, a couple settings might not apply due to the already lower fps on the 5D3, although then again maybe the longer mirror blackout puts it back into a similar scenario?)
I don't know that they yell louder, they just don't want to lose any face with the serious sports crowd who almost jumped ship after the 1D3 (many did, for a while at least) and they have to respond to that, the 5D3 user they can get away with not responding to on this since they can still point to it working better overall than on the 5D2 or 7D.
Perhaps it will come to the 5D3, although last time they mentioned both in the same release (maybe they figure they get less flack for holding off 5D3 if they simply announce it much later rather than upfront put clearly placing it after the 1DX?).
The EC thing should've been done ages ago.

No they are not the same, anyone that knows about 'threading' understands that TWO CPU's can and do process threads quicker than ONE CPU doing all the threading...easy stuff...comp sci 101...sorry you are incorrect...more pipes equal more throughput...the second CPU does offload part of the processing...a wild arse guess says this might make the coding a bit more streamlined and faster...and distributed thru all CPUs.
Unless these are single-threading CPUs...which I highly doubt
And, no doubt the 'extra' coding could be extended to lower models, PP's list; 1DIII/IV, 5D2/3 and 7D seem reasonable, I doubt anything but the 5D3 will get the extra effort; monies if it's deemed viable 'bottom-line-wise' by the bean counters...newer models will as well, like the yet released 1DXs, 5D4, 7D2, etc.
