Why no ULTRA wide primes??

As I understand them, these questions seem to be confusing two separate issues:
1. Short-register mirrorless cameras (especially without angled microlenses) do not play well with wide-angle lenses, and
2. Mirrorless cameras generally don't update the view well enough for effective action photography.

But to answer the questions anyway: "Yes," and "It depends on the photographer."

Laurentiu, there's a nice example (with a 28mm lens) three posts below one of your posts (03-15-11, 05:59 PM), in this thread:

Retrofocus wide-angle lenses do a better job of covering a digital sensor.
As the K-01 shows, you don't have to have a mirror flopping down between the two,
but mirrorless doesn't yet work well enough for serious action photography anyway.

Absolutely. It might do better there than on the NEX,
where the edges looked weak in the Photozone test:
