Fortunately (I would hope), it's our innately human nature of 'inquiring knowledge' that drives us to seek out all we can get on the Pa3X and any other arranger keyboard(s) of interest for that matter.
It's Korg's responsibility (not ours) to manage & control what information gets disseminated out there.
The cat's already out of the bag.
If this requires Korg now to put up Official Demos earlier than originally scheduled, then so be it. The success of their product may depend on it.
