Some more information on the Korg Hungary
site (of all places). There are two great high res pictures here. The upper half of the top surface seems to have a white (metallic) finish.... I don't know what to think of that, but I am quite sure it won't effect the way it sounds
The official specs are also here, but all in Hungarian.... Can't make much of that.
I stumbled upon the link when I searched for news on the PA2X on the Korgforums.
