It's going to be a great loss to many users of the Audya if it doesn't have a style creator/editor.
Maybe some beginners don't use the "style from scratch" but most of my clients employ Yamaha's easy to use Style Assembly, and Style Revoice, so I dare say most Audya buyers would expect the same level of style editing...especially on a $5000 keyboard.
