Originally posted by Raffwal K-01 on the other hand shows a lot of promise in my opinion. I wouldn't buy a MILC without a viewfinder, but perhaps the next model will have one. Using the K mount makes the cameras thicker than MILCs with new mounts, but the market is different for Pentax compared to for example µ4/3 and NEX. Those two already more or less split the market between them, leaving some niche for higher end products like the Fuji which will not sell in large quantities. Coming this late to the game Pentax with a new mount would be left with what drops from the table of µ4/3 and NEX. But using the K mount makes it a potential mirrorless system (with AF) for people with K mount lenses. And I actually find the new deeper K mount lenses a clever thing. Take advantage of the missing mirror and make thinner lenses that protrude deeper in the body thus reducing the whole thickness while allowing the use of older lenses. And it seems that the flange focal length of the K mount would allow much thinner cameras as well like we've seen with K mount film cameras. So when they manage to make the electronics and SR smaller, there's room for further size reduction.
I don't believe in the K-mount mirrorless strategy, for one Pentax K-mount market is much smaller than Pentax can get if the reach for the whole MILC market. It is in this market that Pentax can offer something unique, not with a system that only is interesting for some of the existing Pentax users.
I just can't remember any successful case of adapting old technology to new formats. Using K-mount for mirrorless seems to mirror what Philips did when they developed DCC, a digital version of analog Compact Cassette with full backward compatibility. So how could they fail?

Pentax K-mount mirrorless can be a good short time solution as it don't cost much in R&D, but if they start to develop lenses that are not compatible with K-mount DSLR then they get into the "worst of both worlds" category. Why use an old mount if you develop lenses that can't be used on cameras the mount originally comes from, not even with an adapter?
Pentax did almost everything right with Q, they just used a way to small sensor. With a big brother to Q with much larger sensor they would be back on track. Just like other MILC use an adapters for backward compatibility for other mounts.
Philips DCC lead to someting useful, but it would be sad if someting like this was the only thing left of Pentax MILC in 20 years.
"A derivative technology developed originally for DCC is now being used for filtering beer. Silicon wafers with micrometer scale holes are ideal for separating yeast particles from beer. The beer flows through the silicon wafer leaving the yeast particles behind, which results in a very clear beer. The manufacturing process for the filters was originally developed for the read/write heads of DCC players."
