Those of you that shoot both cameras, am I correct that as ISO's climb and the light gets dimmer, the 1D4 should significantly out-perform the 7D? I've always wanted a 1-Series, but $3K is a lot of money for me, and I need to start talking myself out of this if this isn't a good idea.

I shoot with the 1D Mark IV and 7D regularly. Virtually everything I shoot is in servo mode with both cameras. While the 1D Mark IV has a better AF system than does the 7D, there isn't as big of a difference in my in-focus shot rate between the two cameras as you might guess. I find that, with either camera, if I'm using solid technique, properly locking in focus, and maintaining contact between the focus point and the subject, those are the factors that play the major role in whether my shots are in focus or not, and they are more important than the differences in the focus systems of the two cameras. When I've been using the 7D exclusively for the past two months with my 400 DO because of the need for mobility combined with reach, I've had numerous opportunities to shoot fast moving action (often) with very busy backgrounds, and I've routinely been getting bursts of 7 or 8 shots with virtually every shot in sharp focus.
Similarly, while I'm also sure that the image quality from the 1D Mark IV is better than that from the 7D, again, the differences are not nearly as large as one might believe from reading forum posts. Without looking at the file information, I cannot really tell which prints have come from 7D files and which came from from 1D Mark IV files.
Thus, I start out with confidence in both cameras with regard to AF and image quality, and, when I'm choosing which camera to use in which situations, the choice is made based on factors other than AF and image quality. If I need a light weight and mobile rig, I'll choose the 7D and my 400 DO. If I am in an extreme focal length-limited situation, I'll also choose the 7D with my 500 and, perhaps, a 1.4x. If the situation is not focal length-limited and if I don't need mobility and portability, I'll choose the 1D Mark IV. Again, neither of the two cameras has let me down in any way, and I have confidence that, if my technique is solid, neither will let me down in the future.
