I think it's funny how the 5dmk3 owners are trying to dream up scenarios where the 1dx isn't that much better than the 5dmk3. Look, if you're making a very nice living as a pro photographer in which I am it's a very easy choice, a no brainer as a matter of fact. What some people don't understand is that spending an extra 3k on a body that could make you that back at one wedding is an expense you will take on without blinking. And Yes, the 1dx is much better equipped to handle weddings than the 5dmk3. If you are shooting weddings for a living and feel you need tons of MP you certainly have a different style than me.
If I could afford a 1DX I would be drooling all over it.
I seriously can't wait to see the magic made with this beautiful beast!!!
