Another: Pentax is doing fine as a company but is beginning to de-emphasize their photo division, or at least moving to a leaner photo division..
Possible explanations that come to mind: demand has suddenly skyrocked and Pentax can't ship fast enough (yeah right) labor troubles, political troubles at their lens assembly plant withholding supply from US until currency exchange rates improve Pentax is having cash flow problems Pentax has a problem with parts supply (plausible if K mount hardware is the issue) Pentax is in the process of moving their assembly operations and the move has disrupted operations Pentax is failing as a company
