"Game changers" do not come arround very often, simply because they are milestones that cost a fortune to create, and they are supposed to set the standard for many generations to come. Usually they make "mini game changers" that show off new technology to test the waters. Anyone remember the Yamaha VL series? Also Yamaha is a larger corporation than Korg, they will be a lot more hesitant to do new things - and they produce so much more than just keyboards - keyboards are probably only a tiny fraction of their revenue. I also think that this NAMM was pushed on Korg USA and they might not have been ready for it. If the PA3X was scheduled for a April release, maybe the demos were planned for the Musikmesse instead of NAMM. I have seen many other demos by the Korg guys where they were far better prepaired. Steve can actually make Michael Voncken look like an accountant when he is in the zone. Also if Korg is talking about creating a style store, and want beta testers for the OS - that tells me that the final PA3X is far from finished, and we might see even more minor features when it is officially released.
