There is a Q&A somewhere on the net where Jim says that he will probably never get to play DFRPG. He says if he would run it, it would be to much like work and if he was playing it, he would be a GM's worst nightmare.
On the other hand he said that he might try and play it during a convention, hiding under some kind of disguise. I'll try to find the Q&A it should be on YouTube somewhere. I bet my buddy Tsunami knows exactly where he said it ...
