True... who knows how this will affect anything. That the camera division went from a 3+ billion deficit to a 1+ billion profit in the past year (and supposedly increased market share 250% according to other forum posters, but I haven't seen that in a news article), I would suspect that the camera division should be safe.
Hoya has also been responses to queries from concerned users reassuring them about the fate of Pentax; that they're doing that at all is probably a good sign. Only time will tell. I'm still planning on buying another Pentax before the year is up.

There's no better way to convince Hoya that Pentax DSLRs are worth not only keeping, but investing more money into development of, than to keep the sales chugging along.
