What do you shoot that you need to do "Deep crops", and how deep is deep? I've always thought Bokeh was a lens property. I've found the 7D files don't hold up to post processing like a 1d3.

I shoot an obscure dog sport you've probably never heard of... and I dont say that in a cool, hipster sort of way.
You're right about bokeh being a lens property, but what I find from my 7D is that b/c the DoF is so much longer, I get less subject isolation, and less of a blurred background. Usually, these dog trials take place on club fields which are surrounded by awful combinations of bushes, trees, chain link fences, cars, and people. All of these factors together make for some hideous and sometimes very nervous backgrounds which simply cannot be avoided.
I do try to work within the limits of my gear, but when shooting my 1D3/100-400, there are times I am FL-limited. Even though the sport takes place on a field, I am only ever allowed to shoot from a fixed position on the sidelines, which means at some point, I am always trying to get one aspect of the action diagonally across the field. Those times usually require a deep crop, and the 10MP of the 1D3 are tough to work from. The 7D is obviously much better, but then I run into the background issue again.
The 1D4 would be the obvious solution simply due to the increase in MP. The 5D3 is an interesting option b/c it is honestly the camera I have been waiting for, but then I'm FL-limited (which, I know, is reduced due to the high MP) and has much slower fps. For some aspects of the bitework of the sport, moving from 10fps to 6fps would result in some lost shots.
High ISO will also help b/c the 100-400 is a bit of a dog in anything but great light. The f/5.6 at 400 kills me more often than not, and even mid-day, I'm having to shoot at 3200 ISO just to get a high enough shutter speed, because most trials for this sport occur in the fall/spring when its overcast and raining. Either a 1D4 or 5D3 would suit this need.
One thing I do use a lot is the AF point linked spot metering of my 1D3. Unfortunately the 5D3 does not have that. I dont know if that is a deal-breaker for me, but its definitely not a plus.
