But not too small, please.
I don't like the fact that fitting all of my fingers on the K-7 grip feels just a little tight. Not sure if adding a D-BG4 grip would change things but I wouldn't want to always attach the battery grip anyhow. The K-7 with the size of the K20D would be fantastic (but same K-7 build quality, please). Please get rid of the rubber doors (look/feelscheap!) and add more manoeuvring space to the SD-card slot while you're at it.
Also, I'm not convinced having no buttons on the left side of the LCD is the best solution. It may save space but I like to be able to operate the camera with both hands in parallel and give the right hand a rest while the left hand can do something.
