I've had a feeling it might be - after a disappointing ride in the Superbike race. Strangely enough, John's just been interviewed by Chris Kinley on the grid before a practice lap & he said: "I'm going to have to have a long hard look in the mirror to see if I want to carry on" after getting "smoked by the new generation coming through".

He obviously has nothing more to prove at the TT (other than seeing if he can still run at the sharp end), but I do wonder if the time has now come when he brings his magnificent racing career to a close?
