In good light the 5D3 will provide superior detail in focal length limited situations (which equals most of my situations, which will be further aggravated by using a 500mm on a full frame body instead of a 600mm). Neither will AF at f/8 fast enough to follow many birds in flight. The killer bird and wildlife body may actually be the 7D MkII, with the Digic 5+ processor and a new gapless pixel sensor.
The 1DX will be KING in low light, fast action situations and/or when no cropping is required. I think it's the ideal sport photog's body. I'll bet they're the go-to body at the Olympics this year.
