On-sensor PDAF, will it be as good as mirrored cameras?

Read this, quite informative.

Quotes:

"Overall, our impressions of the Dual Pixel AF system are pretty positive ... it offers clearly greater accuracy and consistency than the conventional AF system. It's worth noting that while you can use AF adjust to fine-tune the behavior of the conventional AF (and may well need this to get usable results), the setting has no effect on the live view autofocus..... those with larger lens collections or who plan to purchase faster zooms and primes will benefit from shooting in live view mode with the 70D. Far from being 'just for video,' Canon's Dual Pixel autofocus does seem to offer a good balance between speed and accuracy, making it a good go-to mode when sharpness is critical, espeically when shooting at large apertures.

Overall, our testing makes it appear the 70D's Dual Pixel AF gives most of the speed advantage of conventional phase detection AF and most of the accuracy benefits of contrast detection, but doesn't quite manage to offer all of both."

The 2007 PDAF set-up in the flapping mirror a700 / a900 is clearly dated in comparison. I own and use both.
