Pat O'Connor was also the director of "Cal", so that could be a little hint for MK to say "Yes".
I honestly hope he has said "No", because for me, his soundtracks are great but they usually mean a delay for the "real" thing which is "real" album and tour. His film work sometimes seems "half arsed" (just listen to "He's The Man" or "All That I Have In The World"). A little guitar here and there to recognize it is from MK and ready... Just my opinion of course, and there are some exceptions like "Wag The Dog", but in general I would be fine with MK never doing any soundtrack again.
