I think some people here have forgotten that this is the FIRST PSR that isn't simply trickled down technology from the Tyros's.

The audio drums, the synced .wav's as multipads is completely NEW. These are hardly 'minor' new features!

Particularly the .wav multipad feature (as you WILL be easily able to add your own content with little to no load time) is potentially a complete game changer. The variety of percussion, breakbeat and synth loops out there is staggering. Being able to add them to your performance pushes this arranger into totally new ground, especially if you are into newer music.
