What do you think

I guess so too. At least that is what mirrorless cameras with mounts is about to me - try to keep it small with good image quality. That is probably also one reason which partly speaks for what I would assume to be low sales for Nikon 1 cameras and also Pentax Q, compared to other mirrorless system available.

Eventually I think that I can see the Canon and Nikon for example, to start putting decent eyeviewfinders into their dslrs to replace the current mirrordesigns.

The K01 might have been a success, had it been less wildly designed.  I hope at least that Ricoh stick to the point of creating their own mount with very short flange back distance sooner rather than later. That would make good sense to me and probably others as well. Them might share that mount with Pentax and cooperate about produce lenses for it.
