Can you please elaborate with more info.
I think that could be a problem; K500 and K50 are not the cameras that drive the sales of better lenses, especially DA* and DA Ltds. To me, K50 and K500 are aimed at folks buying kit lenses.
To sell more quality lenses, Pentax needs APS-C cameras that are clearly advanced enthusiast and pro level. When they have such cameras, then sales of lenses will go up too, and K50 users will suddenly see an extra appeal in better lenses.
Or, two more APS-C DSLRs are needed. In total, four. Just one body above K50 makes lineup still very weak, wanting and is same as what we have today.

The issue right now is mainly that there isn't enough separation between a K50 and a K5II. They sport the same sensor, viewfinder, and are pretty similar in specs -- the K50 is actually better in some respects. Having a low end cheap camera in the line up is good. There are a certain number of people who buy a Canon XSI or a K500, who eventually decide they want to "get into photography more" and will move up. The more K Mount users the better in my opinion -- even if they are just buying used K2000s on the marketplace.

@Uluru: Listen to Adam's translations of recent interviews and read recent DPI articles for confirmation. Your time horizon is shorter than Pentax's business plan. I would not be surprised to see a new APSc dSLR higher-spec'ed than K5II before much time passes. I would not be surprised to see something above that but below the best Nikon before much more time (but I can't hold my breath long enough for the latter).
As always, what difference do the bodies make to lens sales if you don't have the lenses to sell?
The idea of low and mid-range bodies - and colors on them -
right now for Pentax is to rapidly increase the installed base of
K-mounts in the hands of the consuming public. They don't care what is wrapped around the K-mount -
just get K-mounts into the public hands.
Once the installed base is large enough third-party makers will start releasing in K-mount again, which will stimulate demand for K-mount cameras, which will support higher-end bodies, which provides cash flow for new Pentax lenses (and high priced 3P lenses) - et cetera, et cetera.
