That the best MILCs are better than the lowest end DSLRs, is true
Pentax would have two choices:
- to aim their mirrorless cameras at the low end, waiting the technology to evolve and growing with it
- to aim their mirrorless cameras at the high end, and suffer because the technology is not up there. They might have some advantage when the technology would catch up, but not necessarily.
Kitazawa-san said their decision has implication in the long term (10-15 years IIRC). They should not rush it, right now they can continue very well with the ever-growing DSLR market.
