I have read a bit further on the UK site, and it looks like they will be bringing out a 76 note version of the Mediastation at the same price point as the Korg PA800 and Ketron SD5, (Typically a third less then the TOTL Arrangers from the Big 3) which should really ruffle feathers, as it means that you can add a couple of High Quality VSTs for the same price of a TOTL Arranger.
Hopefully it will appear at Pakefield, allowing real players to make the decision on its capabilities.
Enjoy whatever you play
