Why would anyone expect to see a big difference in IQ?
It's never been that way, instead we get more features, marginal "IQ" improvement, mainly in the high ISO noise department, and that's about it.
My interest in the MKIV is about getting more resolution, hopefully 1 stop improvement in high ISO noise, nice LCD (LCD on the 1DMKIII is crap by any standard), possibly video...and of course all the other things that typically comes with a 1 series body...build, seal, battery life, form factor, speed, etc.
I agree. I'm particularly interested in whether his claim of very responsive AF in low light conditions holds true. How many people remember the complaints about the 1DII hesitating slightly in very low light, particularly tungsten light? Such as at wedding receptions, etc. I know I experienced it from time to time. I definitely found the III better, especially for low light sports, but there was still room for improvement. If the 1DIV can AF track a bride walking down the aisle when shooting with the 85L at an exposure around ISO 3200 1/200 f/1.2 with most frames dead on sharp, I'll be very happy.

100% crop. The AF has nailed the image even with using one shot and a moving subject.
What... we're to think that the AF on this camera is so unbelievable that even One-Shot can track moving objects? Or are we to think the operator doesn't know when to use the various AF modes?
I've been using Canon long enough to know that getting an in-focus image using One-Shot with a subject that is moving towards you is mostly luck.
Your taking it out of context. He didn't claim it tracked in One-Shot. He never claimed to have shot a sequence in One-Shot where all images were sharp. My take on it is his first and possibly only frame was sharp because the camera was fast enough to make the exposure at the moment the focus was locked. Remember that Canon is touting this camera as needing zero time to calculate AI-Servo tracking, so that probably spills over into very fast and accurate One-Shot acquisition. If one was to make the exposure the instant One-Shot AF locked focus, then even a moving subject could be in focus (and it's not like someone walking is the same as tracking a BIF or a moving car, etc.). I have definitely done this with the Mark III, having accidentally shot sequences at the start of a sports event in One-Shot, and the first frame of each sequence was sharp.
