The K-7 sensor was enough for Pentax to wave good bye to Samsung and get on board with the sensor manufacturer that had the current performance advantage and seemingly the momentum to continue to pull ahead. I think the last 2 years have shown it was a very wise move.
could be or the other way around. on Samsung's side, I think it is pointless for them to keep the partnership with Pentax, especially if they are offering the same cameras for sale in the market (GX10 and GX20 versus K10D and K20D). for the most part, the sales would mostly go to Pentax and it's lenses since Samsung is only practically selling their cameras. it could be that Samsung has already garnered enough info from Pentax to start their own line of lenses and leave Pentax in the dust fending for itself. the K-7 would had been probably the last remnant of the partnership and I think this is the reason why Samsung came up with a mirrorless system rather than releasing yet again a renamed K-7 (maybe a GX-7). this could be the reason why Hoya was able to acquire Pentax easily.
if we are going to evaluate things further, the K-5 practically is a rehashed K-7 with a different sensor and a few tweaks on the AF. there is no real innovative change so far aside from sensor change. and about the lenses? well, a rehashed 35mm, a re-release of the FA20-35, FA35, A50/1.2 and finally an overpriced kitlens with a new motor (DA18-135). so far, Pentax has been behind in the lens game. I'm not sure what advantage would Pentax obtain from going mirrorless aside from keeping the faithful happy with having possibly a small camera alternative. but still the question remains and the lack of new lenses, how are they going to improve their AF system? I'm sure they can retain the screwdrive function for backward compatibility of old Pentax AF system on a new camera. a sort of engage function one's an old lens is mounted on the camera. all they need is to change SDM with an efficient, quiet and faster one. it could had been the SSA system, but I guess Samsung kept that technology for themselves as a leverage for their own unique product.
