Well, 8-ball says if you continue to drive your X, your tranny will break some time in the future and it will be expensive to repair.
Not sure how anyone can predict what will happen to your car. Some trannys break at 30k and one guy here has nearly 200k on his without ever changing the fluid. There really isn't anyhting you can do to prevent it from breaking. If you plan on keepin the X forever, I would start a savings account for repairs.
