Rupert, I agree and I certainly don't fault you for writing that. I also understand your message; yet I don't understand why should we even talk about stuff like that. With the current product portfolio, why would I be anything but (mildly) optimistic about their future?
Why the worst case scenario?
Our only real disagreement is about Hoya; which IMO are serious about Pentax, and quite competent too. Time will prove me right... or not
I know Samsung are very capable, but I wouldn't go as far as to believe they will necessarily succeed in everything they're doing. Until now, they failed to impress me - talking exclusively about "serious" cameras.
You, OTOH, are overestimating them - even the whole Samsung group can't "buy out Nikon, Canon, Hoya and even Sony...with pocket change". They are big, but not that big - besides, we should talk about Samsung Imaging - which may not be able to buy even Pentax.
Rondec: less than 18k units per month
Hoya would not launch a camera without being sure they'll make a profit.
