Originally posted by Kunzite 3 years, on a stable company, and maybe they had previous research leading onto that. Ricoh Imaging had to struggle with the merger of Pentax Imaging Systems and Ricoh's own camera division, and with fixing the sorry state they were left in by Hoya. Only 3 years and 3 months passed since Ricoh took control... we should keep that in mind. Yet we had the K-3 and the 645z.
"IMHO mirrorless is going to win over DSLRs" - perhaps, eventually. Perhaps photography and cameras will be banned altogether, before that.
Right now I'm glad I can still choose a superior solution
Ricoh is more of an off the shelf camera maker though. Samsung developed literally everything for the NX1 new, while Ricoh gets a couple of parts from Panasonic, Sony, ... Still, 3 years is about right. I think the really interesting one will be the next launch. That should show us the direction they are going in.
I also prefer DSLRs over mirrorless at this point (maybe the NX1 can win me over... I wonder why Samsung hasn't made big box retailers here stock the camera...). But the time will come when mirrorless is simply better in most if not all areas, and Pentax might want to get into a better position for when that switch happens. Will Canon users, and Nikon users, when they have to switch systems because mirrorless makes more sense, still be getting Canon and Nikon? Or will they look at those brands, and the small amount of lenses etc. that are being offered, and then look at Panasonic, Olympus, Fuji and perhaps Sony and see how well positioned THEY are and how experienced they are with mirrorless, and decide to switch? Who knows how far loyalty goes.
That being said I don't see Pentax doing APS-C or larger mirrorless any time soon. The new 18-50 kit lens is quite telling IMHO.
