The camera certainly looks nice. However, I become a little uneasy when reading about all the stuff that is supposed to move around inside. How long will that technology last?
Another interesting question is about what lenses are available to the camera, and how good they are with this level of camera resolving power. A comprehensive native lens line does not come into existence over night - nor is it cheap to develop from scratch. Of course you can use adapters and third-party lenses, but much of the desired feature set of a modern camera is lost that way and who wants to boast they have reverted to the '50s for features? (this with the caveat I really don't know what gear Pentax offers at present).
