Not sure if this is pertinent, Scott, but on the Korg site, a forum member tells me that Jone of the Korg PA3X owners comment on the video was as follows,

"He plays good. But most of these styles I don't have in my PA3x."

I suspect vanderstel100 is correct about the extra styles being part of an update.
