Since I have only been using fixed lens digicams for the last 6 years I will not comment as fully as I should but I definitely would want based on what I do know:
The following: 1. Full support of all FF pentax bayonet mount lens functions (surprise?) APS lenses to of course if the sensor is APS 2. More MP. I havent seen ANY 6 MP images to get too exicted over. If I was a pure 35mm film user I proably would be satisfied with 6MP but I have been exposed to and gotten accustomed to LF too much to find 6MP fully satisfying. 3. Better viewfinder for APS, these are too tiny to my eyes. If it means a higher magnication finder with lower eyepoint and mandatory diopters, Id rather have that because by 35mm SLR standards these are too tiny. 4. USER Interchangeable screens. I like the ability to change as well as if not even more the fact you can easily clean them ( NOTE- this might be in error because they have them already? I am not sure). 5. DUST control features if possible- arent there some sensor self cleaning techniques on some other DSLR cameras now? 6. Bigger or FF sensor- but only if cost is reasonable. I wouldn't pay an unlimited amount of money to get this but even if at same pixel density, its better in two ways lens angle maintenance and lens resolution utilization. That's about it for now....
