I think that the best takeaway is that Canon split the pixels in half for PDAF (or DPAF), and image quality didn't suffer at all. That's a big thing, really, even though they're still missing out on DR (which I agree that they need to fix ASAP).
The positives here are that the 7D II, if it uses this exact sensor, will be at least as good as the 7D with respect to dynamic range and high ISO performance- while putting out noticeably (if only) better resolution from high-end glass, and that future PDAF-based sensors for the Rebels, the M's, and the P&S's will be much more usable in Live-view mode- a real big difference for the M's and P&S's that will bear out quickly in AF comparisons, even if literally everyone else has better DR.
Now, if you apply these results to FF sensors, you have a real reason to be excited. Provided Canon is willing to put in the elbow grease to improve their processors and firmware, there's a real possibility of a DPAF implementation providing far increased resolution while making single-shot LV shooting completely viable in many situations, including fast action and birding. Super high-resolution PDAF (at least 85% coverage?) and intelligent subject tracking would mean that you could have the camera follow-focus on a player on a field or a bird in flight by designating it and then keeping the player or bird within that 85% area- I'd be willing to bet that it could keep track even if you lose the subject and then quickly reattain it, as long as the subject's lighting and contrast hasn't changed considerably.
