I do not normally comment on developments I have no inside information about. It is just adding to the noise in the internet. Here, I decided to make an exception :)
So, Canon launched the Canon 70D digital SLR camera 2013, July 2, two days ago. It includes an autofocus technology named "Dual Pixel cmos AF" which promises to introduce high-speed autofocus performance to live view shooting and movie recording which previously would have required a phase detect AF module, at least in lower light situations.
I believe that this innovation looks much more innocent than it actually is. Here is why.
