I feel it necessary to point out: Just because the K-x uses a Sony sensor does not in any way mean that Pentax's relationship with Samsung's sensor division has soured. Look at the past: All the while Samsung sensors were used in the top-rung K20D and K-7, Sony sensors were used in the entry-level K200D and K-m. The fact that the K-x now also has a Sony sensor doesn't really imply anything about any changes in the previous pattern and relationships.
On the other hand, we have knowledge now of further-developed Samsung APS-C sensors on their way, and if the past patterns are any indication it would not be at all surprising if the next upper-level Pentax has a Samsung sensor and the entry-level stays with Sony sensors, just as in the previous two generations.
The 14mp Sony sensor from the A380/A450/A550, however... I really hope not. The files from that sensor have not impressed me at all. The newer iteration seen in the NEX cameras, however, seems to have the characteristics of a slightly improved, higher-resolution K-x sensor. I would very much like to see that sensor or something similar in a Pentax camera.
