K-200D same controls and OVF as K-m, larger body, WR
K20D and K-7 had similar feature set to K-5
Pentax hasn't had 3 dSLR bodies in production at the same time for very long. The K10d was still on the self when the K20d and K10d was released but it wasn't really in production. The K200d was a unique model in that it was a "mid" WR body. They hadn't done that before or since.
The K200d had a Penta-mirror and 1 wheel and WR and an improved version of the K10d sensor. . I bought one when the first come out and a K20d a little later. However, the K-x and K-r never shared sensors whit any previous flagship dSLR. The K-m/k2000 was at the very tail end of the K200d and am not even sure if the K200d was even still in production so the used up the sensors in the K-m. The K20d sensor was held over for the K-7. The K10d and K20d shared body styles but a new sensor in the later. The K-7 and K-5 shared body styles but not sensor and AF. It is a very good possibility that the new flagship body will have some changes as well as a 24mp sensor.
Back to my question, what would be the difference and advantage in a entry level 16mp dSLR and a WR mid-level dSLR other than WR other than the possibility of a penta-prism and 2nd wheel. The other option would be to cripple the entry model in some way. The other possibility would be to put the 24mp in a mid-level single wheel penta-mirror WR body.
