Nikon drops sales forecast as high-end camera market stalls | Reuters
My guess things are no better at Canon and Sony - they are just cannibalizing each others market. I am not sure how Pentax is doing financially but spending millions on advertising and selling equipment with little to no margin doesn't make sense to me. I am happy Ricoh is moving Pentax forward, introducing new cameras and lenses.
Buyers pick Pentax because the cameras provide the best bang for the buck.
The demand for high end DSLR's is declining and Canon and Nikon need to continually bring out more high end systems nobody is buying in sufficient numbers to warrant their production. This provides a lot of sizzle and attracts people to buy the lower end, low/no margin of their product line in COSTCO, BEST BUY, TARGET etc. The old adage of not making profit on your products but making it up in volume.
Again, I am happy Ricoh took over Pentax. I am planning to buy the 1.4TC soon. I am waiting to see what the new telephoto zoom looks like.
The only area that I would like to see improved is more support for Sigma's product line on Pentax or more high quality Pentax lenses at the long end - since I enjoy wildlife photography.
