In fairness, Rikki, the PA5x is not a completely ground up, utterly new product. Some of the hardware has been seriously revamped, but the underlying OS is very MUCH a continuation of everything Korg has done for decades. It’s just horribly bugged and massively incomplete.

But once the missing stuff is added, and the bugs addressed, there’s very little from workflow to editing screens that will make a PA4X player have the slightest problem adapting. Certainly no more than the PA3-PA4 change did. I think you are being a bit forgiving to Korg. But then again, not being dependent on data migration and being able to immediately gig on your very expensive purchase puts you in a small field of users that can AFFORD to give Korg all the time it wants. Others are not so lucky, and nothing makes them madder than trying to take the heat from off Korg’s feet!
