Better off going F/4 at that point and saving cash. 70-200 f/2.8 IS II on a t3i is like Snow Tires on a Ferrari... Sure it works, may be better than nothing, but sort of missing the point.
I'm relating to personal experience. I got hooked on the 70-200 f2.8 by using a Mark I verson on my XT and on a friend's T2i during a figure skating ice show lit only by spot lights. I had been using a non-L 70-300 f4-5.6. The f2.8 was critical to getting reasonable shots and a huge improvement over the 70-300. It also improved the focusing performance of my XT. In my case, I upgraded my XT to a 60D then added the 70-200 f2.8 II. Had I owned the T2i, I would have done the lens upgrade first. The T2i/T3i shares the same sensor with the 60D and 7D. This offered the low light performance that I was lacking with the XT. Center-point focusing on the T3i should benefit from the 70-200 f2.8L lens. No question that tracking and buffer won't be as good as the 70D, but for casual sports, it's still workable.
Since the OP referenced sports shooting with his son, this likely means indoor sports. I would rather shoot with a T3i/70-200 f2.8L II than a 70D/70-200 f4. Of course, I'd rather have both the 70D and the 70-200 f2.8 II.
The OP referenced a need for a 70-200 lens, a fast 85, and some sports with his son. The 70-200 f2.8 II will satisfy these needs. In my opinion, if the OP goes for the body upgrade now and a 4.0 zoom, he will regret the zoom purchase and eventually seek to replace it with the 2.8 Mark II version. If he can't afford both a body upgrade and the 70-200 f2.8L II now, start with the lens and do the body upgrade later. The 70-200 f2.8L II is one of those lenses that can bring out the best of any body.
Funny, I read it as shooting sports with his son meant outdoors! (American Football, Football, lacrosse, marbles)
