Hi Sam

On the PSR9000Pro, I have no more information than you do, but here are some guesses anyway. We will all know more in a week as the European introductions are beginning.

The mic implementation on the Pro will be more sophisticated than on the non-Pro. They probably moved the mic controls in response to complaints from people who feel the way you do about the accessibility of the modulation and pitch wheels. The PSR9000Pro will not have speakers, but will only be slightly lighter than the nonPro, about 10 pounds heavier than the PSR8000. I doubt the sync/start buttons will be moved. Note that you can control this and other functions with a foot switch if they are not where your hands would want them.
