I shoot sports too. A sports body like the 7d with a better sensor than what you can squeak out of an aps-c, plus the frame rate is a perfect matchup for what i do. The 7d sensor is seriously lacking but the focus system is tops. Some people don't understand dreamers, dreamers come up with ideas that may not fit but when something is done with those ideas companies like Apple become successful. I am not here to give stats, show evidence or make a case. For the reasons i have stated these are my dreams. I really am ok with people having their differing views. I encourage the discussion, but no one is going to demand or make me prove my idea lol. Who does that? I just don't appreciate that because i throw an idea or a concept out there that i need to prove its a good idea, i mean really, that doesn't encourage great discussion...
I realize the aps-h is probably done but i will say if it were my decision i'd either upgrade the 7d with better sensor tech beyond the limits of aps-c, possibly even FF or create a new camera model. If people say its a 1dx killer then its probably the perfect idea because we all know thru history with Canon and Nikon that there is plenty of market for both to exist no matter what people are saying about one killing the other. Every d series body should have a smaller cousin that has a few less features and are built well but obviously not a d series level of build i mean my camera has fallen to the concrete a few times thanks to my R Strap malfunctioning (by the way i don't use the Rapid strap anymore its all about the spiderpro holster) and i pick it up and it just works. I have shot in in rain for hours with my 1dm3 and the only issue really was a foggy eye piece. The D series gets the heavy duty parts for extreme environments. Canon knows what people buy and why. A person won't buy a 1d series unless they want it or their jobs require it be able to handle extreme environments. Everyone on a budget or just wants to work with lighter gear will buy the smaller alternatives. Now that they merged the lines there has to be a viable alternative to the 1dx. The 5dm3 doesn't have the frame rate required for that in my opinion, the 7d does its just that it is lacking sensor capability.
