Exactly what I was thinking. The 16mm long end stops where a number of Nikon standard zooms start. The same is very close for Canon. The situation is the same for the 12-24mm. Both Canon and Nikon possess a number of 24-XXXmm zooms.
This situation reminds me of the pleas that spring up from time to time from the DA/FA Ltd. prime folks. "We want a XXmm f/0.95 to fill the gap!"
As Adam stated earlier, there's no reason Pentax can't make a 10-20mm lens. I would hope, however, that any ultra wide lens Pentax releases at least makes sense in the lens line up. The road map indicates a DA* standard-ish zoom with a little more reach than the 16-50mm. Nobody has said definitively if it will be 18-80mm, 20-85mm... Even if the DA Wide Zoom on the same map isn't a Star lens it would be nice to see that lens sync up, closely at least, with existing glass.
