these are very great comments,
since I have no idea what I'm getting into and it's based on the sports that me and my wife play and friend's/photographers who've taken our photos playing these sports, just as a general guideline
Although you're right, he's only 8 months now, so it'll be a while before he's doing any sports and even at 3 years old, I'm pretty sure my 5dmk3 is sufficient.
I just wanted to hear the flip side of a 1dx or 1dx2 whenever that comes out,
the stuff i shoot is normally stationary and doens't require any high fps
