I'm not suggesting that this will be the final evolution, merely a tipping point that I suspect will see Canon's mirrorless offerings take off. Pros are going to be very reluctant to start buying several thousand dollars of lenses in a new and unproven (longevity-wise) lens mount, but may well buy a $1000 camera if an adapter lets it accept all of their existing lenses, keep the same focal length, and also turn their 16-35mm f/2.8 into a 16-35mm f/1.8.
