I agree with all the praise of the K20 thus far, and like Scott, I was an early adopter. Still, there's room for improvement without a complete redesign, especially for those of us who like to shoot sports. If a K30 is coming, I hope they address AF issues and develop a faster fps rate at full frame.
However, Ed, you don't need to be salivating over my K20 should they come out with an irresitible K30 with the improvements I seek. What was it Charlton Heston said when he was president of NRA, "Out of my cold, dead hands."
