I'm not sure that it didn't succeed... though it certainly wasn't the most popular Pentax camera when it was current - yet it has a bit of a cult following now
I think there are several reasons why it wasn't
more successful:
1) It's size was about the same as an APS-C DSLR without the viewfinder prism - basically, because the flange focal distance for K-mount was maintained; and, as such, it was big, thick and boxy for an APS-C mirrorless camera compared to the likes of Sony and Samsung's offerings (for example) - whilst for existing Pentax users, there wasn't a significant size advantage over, say, a K-5
2) AF was leisurely due to CDAF only - no PDAF sensor was included
3) It was a little bit too "fashionable" in design, with the whole "Marc Newson" tie-in
Nice camera, though
