FWIW does the D7 have full weather sealing? That is my biggest concern right now,
Are you asking about the nikon d700? If so, yes it has weather sealing.
most of canon's AF issues can be "fixed" by going to AI Servo, Center Point AF only, with expansion on, well at least on the 5DmkI.
Then there isn't much point in having more than 1 AF point, if you can't reliably use anything but that single AF point. I buy cameras with more AF points because I want to use all of those points. I can and do, with my cameras.
Letting the camera pick the AF point while shooting hockey or baseball isn't a wise choice no matter which camera you pick up.
That is simply not true. It may well be true for your camera, but it certainly is not true for many nikon bodies, especially the d300 and up. Even the older or cheaper bodies with group dynamic AF work very well.
I'd suggest that you get with someone that owns a camera with pro AF and let them give you a good demonstration of what a good AF system will do. I'm sure that the canon pro bodies are quite capable in this area too and hopefully, the new 7d will give you guys a good AF system that won't restrict you to the center point.
