Sano - How do you know the inner workings of the RSNA? What if there was a cancellation fee of 50% within 'X' amount days before the show? IMGG, like others, thought it would have been a sealed deal by then. I, for one, wouldn't have missed the show for the world (if I was Dean) if I had FDA approval going into it. This is only a possibility. I don't know the inner workings...neither do you.
