Well, I think that over the course of a full year I doubt I shoot more that an average of 200 shots per week. That is about 10,000 per year. At that pace the camera will be 10 years old before I get to 100,000. I bought the DS a little over a year ago. 1.5 years later the K10D comes out and if I could afford one it would be in my hands now, but with well less than 10,000 shots on the DS.
Unless you are a pro with a staff to help you process your shots, I doubt you could reach 100,000 in less than 5 years. By that time a fancier, sexier camera will be out.
