Mk III AF rumbles--any users out there?

I am on a list to get one of the Canon Mark III's and have of course been following all the net chat about the AF issue (or non-issue) and was curious if anyone out there has personal experience using the new Mk III on rapid moving wildlife (think birds). I have a Mk IIn and have to admit to being befuddled from time to time with the AF system. I am a recent convert from Nikon and attribute most of my AF fumbles to that.
So any real use observations of the Mk III AF capability? I searched the forums here and couldn't come across a string on the topic.

Thanks

There are a mixture of Canon vs. Nikon users here, but for the most part the camera owners are using 5D and lower units.

Yeah, I don't think we have any Mark III owners here yet.

Well, DPR***** & FM is full of posters saying it's not working right. And Ron Galbraith claims there is an issue as well. If I were you, I'd stick with what ya got until this is all figured out. This of course depends if you need it for business reasons, but the MarkIIn ain't all that bad until then!

But I must admit, I have a 5D and do not have plans to get a 1D anything anytime soon.

I have both a 5d and MK III. Sorry to confuse you even more, but my MK III focuses just fine. The "birds" I track are actually brides and grooms walking down the aisle. But just as an exercise I have tracked focus along a telephone wire crossing the sky. As long as the background is normal sky, it is fine, but the moment there are tree branches behind the wire, the focus instantly jumps to the tree branches. I imagine the same issue could exist tracking birds flying in front of trees. The camera will almost certainly lock onto the more strongly lit subject, whether bird or branch.
Oh, and just as a reality check on Ron Galbraith's reports that are so often pointed to, just make a note that he has selected sunny days with very contrasty lighting, and very warm days in the upper 80's to finally locate the conditions where the camera has trouble deciding on which object to focus onto - all while shooting at 10 frames per second. Conditions any nature photographer would normally avoid like the plague.
I suspect Canon must be pretty pissed off at him. Note Galbraith's recent post that he was holding off on printing a whole new series of photographic "proof" that even with the firmware upgrade, the camera still can't get it right. What a coincidence! He just had a little chat with Canon's PR man.

Thanks to all who replied. As with most technology, it is hard to separate the 'nits' from the realities of use. I guess I will have to flip a coin when my name bubbles up to the top of the buy list and decide if I go for it or wait a few months.

Thanks!

Oh, and be sure you note in Galbraith's method he only shoots at a wide open aperture to maximize the focus error he is looking for. So if the focus is off a tad bit on the jersey number of a sprinter running toward him then it's another black mark against the camera. When is the last time you intentionally set a shallow depth of field for tracking a fast moving subject? And why would you ever need to do that when you have an abundance of light? Oh yeah, to prove beyond a doubt that the camera has major issues.
