What do you think

Are you saying because it's the size of a small DSLR? Well, that's because it's exactly what it is. It was never meant to be smaller like a CSC. So it didn't sell because you and DPR and everyone else compares it to a CSC, where it obviously fails by beiing too big.

So Pentax failed to position it properly and creating a whole new category for it, the DSLnR, where it would shine as the most compact DSLR on the market.

So things sell relative to perception of how it compares to it's competition, so Pentax needed to define the competition better instead of letting reviewers like DPR do it for them and lump the K-01 in with CSCs.

Much like the positioning Nikon and Sony took with the 1" sensor. Nikon positioned it against CSC where it looked abysmally small against m43 and APSC, while Sony positioned it against enthusiast compacts where it looked absolutely huge against the much smaller 1/1.7" sensors. Resulting in the Nikon 1 being panned by the photography community as a step down yet the very same sized sensor in the RX100 universally praised as a great leap forward.
