The concept image for the 6D AF is interesting. It's more wide-set than I anticipated.
From Canon's product page:
High Performance Composing and Focus
The EOS 6D has an entirely new 11-point AF system for fast, accurate AF no matter the situation. With its new centered cross-type AF point with EV -3 sensitivity for improved performance and focus in low light, and a newly developed and bright 21mm eye point viewfinder with 97% coverage, the EOS 6D offers impressive performance in both composition and AF, even in the dimmest lighting situations. Offering not only One-Shot AF, AI Servo AF, and AI Focus AF, the EOS 6D’s AI Servo focus can be customized with tracking, acceleration and deceleration tracking sensitivities, and 1st or 2nd image priority adjustments. For even more customization, adjustment levels for the wide-angle and telephoto ends of particular lenses can be entered and recorded into the camera’s memory.
