What the video and the a6000 are showing us, is that on sensor phase detect systems utilized by mirrorless cameras are able to achieve and refine focus quickly enough to track motion reliably. Whether or not that translates into the ability to shoot sports remains to be seen.
That said, the AF tracking systems that make sports and wildlife oriented DSLR's so effective at what they do has nothing to do with the fact that they have a mirror. These AF tracking systems are dependent on software driven algorithms, and how capable the camera's processor is at handling these software algorithms. There's absolutely no reason why an AF system designed to track focus along phase detect points placed on a mirror, couldn't be adapted to track focus along phase detect points placed directly on the sensor. In fact, there are distinct advantages to placing phase detect points on the sensor....one being that you can place them across the entire sensor, and can track your subject across the entire frame.
Another advantage would be that one source of focus error, misalignment between the AF sensor and the image sensor, would be eliminated.
But that is in the realm of the hypothetical. Here right now in the real world we have the following situation:
1) Nobody has made a camera that is competitive with SLR technology for the most demanding AF applications. Maybe this is because nobody has bothered. Maybe this is because there is a technical limitation. Whatever it is, there is not a single mirrorless body right now on the market that can do what SLR bodies can do for AF.
2) Nobody making mirrorless bodies is offering a full line of lenses that rival's what you can get from the Nikon and Canon SLR lines. Give me an EOS or F-mount capable mirrorless body with no limitations on AF performance (even if there needs to be a spacing adaptor) and this gets better. But right now, Fuji, Oly and Sony are not in a position to make "DSLR Now Obsolete" as suggested by the title of this thread.
I have no fundamental problem with the idea of a mirrorless camera so long as the EVF gives up nothing in terms of lag and view compared to the OVF, the AF performance is really the same, and there is a full lens line from TS-E to supertelelphotos to macro to fast primes to the fast zooms needed by working photographers. Then the title of this thread starts to make sense.
I will also suggest that a certain level of hyperbole that comes with each mirrorless camera is hurting the cause more than helping. The earlier Sony A-mounts touted 12 fps.....and then we learned they don't track AF or update the EVF during the burst. The A6000 now touts "fastest AF ever", but I can tell you it is not a camera I would grab to shoot a basketball game. These hyperbolic statements are hurting adaptation IMO, because demanding people just keep getting more skeptical.
