Betcha this is why Canon went with a stronger AA filter.
That is just sour grapes talking. The "pop" you talk about with 5Diii is its lack of DR. High DR images have flatter look and you can post-process (the horror!) to make it fit your levels.
By the way, in your original post, why did state that you did not photograph anything of "super speed?" Car racing, especially drag racing is definitely super speed for a camera.
My 30D is okay at shooting the drags, not perfect but okay. I would hope the 5D II would be better than my 30D.
When i shoot sports its always small jpegs. Ya need the buffer and ya don't need a tons of info. Even at 1- 1.5 mg our lab uses fractals and creates nice poster sized images. Our prints really do look excellent. For weddings, i don't worry about buffer or file sizes.
I shot a car race recently, and afterwards, the client wanted to downloaded jpegs straight onto his laptop. I know only amateurs and soccer moms shoot jpeg, but the ability to hand over high quality jpegs on a whim, when you don't have to opportunity to touch raw files up in post, is a huge benefit at times. To me, the out-of-camera Nikon files look like ass. That would bother me a heck of a lot more than, and take up more of my time to fix in post, than the 5DIII's disadvantage in DR.
The strange thing is that most Pros I know switch to Jpeg once they are shooting events where they are taking large amounts of pictures and not doing dedicated (set up) work like fashion or product photography (when they usually would not use any equipment currently offered by Nikon or Canon ... MF anyone ?), as they also don't have the time to work with hundreds of raws ...
On a side note imagine the following not completely unimaginable scenario: Doing a one to two week photography trip where you would take 5 to 10k pictures ... do you still like 80MB raws afterwards with you limited processing power of a consumer notebook/mac ? I really don't think so and that is for what I need and want my camera to function perfectly ...
I am tempted to shoot both and use jpegs unless i need help with some files. Like the guy said in the video when he is done with editing the raws they pretty much look like jpegs anyway. The 5dm3 jpegs i am getting havent needed post processing which is pretty dang phenomenal but then i havent shot in a 3 diff light source poorly lit stadium either.
I wouldn't be so fast to laugh: Of course the 70-200/2.8 is an excellent lens, but imho has some drawbacks: a) physically larger, front-heavy on 60d, less suited for travel, b) no IS which is handy when some animal doesn't move for some time, c) very small depth of field on 2.8 - even when a bird is looking towards you, you need something like f5.6 if you want to have it in focus, d) more need for a good af and af micro adjustment (i.e. not the 60d)
One thing that helped me when I first got started: I bought a 50mm f/1.4 and just stuck with that on my Rebel for a long time. It helped me really get a handle on composition and forced me to recompose with my feet, instead of just zooming in/out. I believe I became a better photographer because of it. You can get a Canon 50mm f/1.8 for like $130, probably the best lens anywhere for the money. After that, you can start deciding how to add to your stable.
My proposition is that iso should be kept as low as possible as a matter of best practice.
The 5DIII's AF [...] it's still not as snappy or responsive as even my ancient 1DII.
