Hey Marsha, alas, Nikon did not "guarantee" any specific shutter count life. Rather, they provided a "rating" as in a minimum expected life. Your camera may last another 170,000, another 500,000, or another 20. No one can say for sure. Don't worry about replacing a camera based on an expected life until the camera actually develops a problem.
A very thoughtful answer.
