Wishful thinking
And your last post has nothing to do with the previous, where you were "guessing" that "Pentax DSLR are the same or shrinking". What are you basing this "guessing" on? My Pentax dealer observed an increase in demand, selling even high-end lenses like the D FA* 70-200. Of course, the Romanian market is insignificant, but things seems to be going in the right direction.
The thing is, Ricoh bought Pentax because their own camera division was going nowhere (sorry, Ricoh GXR fans!). With Pentax, they managed to turn it around, making it a profitable and growing business.
You are most likely right about the Theta growing, but then again, we have hints about that as well.
