Here's yet another Korg Pa3X YouTube clip just uploaded of it played in a music shop in Romania.
It also includes another guy playing a Korg Kronos, at least according to the YouTube clip description. They are playing a Manea style of music.

I can't figure out how these keyboards are already showing up in music shops before their official release date.
Does Korg know/care about these Youtube clips?
I also still can't figure out why nobody's recording via direct line out instead of simply thru the add on speaker.
