If so (but I stand my former statement ), than the OS versions 1.xx will be free. If, and only if, there comes a OS version 2.xx /1.5 the customers have to pay for it. Something like Yamaha does with Cubase (which he owns). Or maybe Yamaha offers commercial (not free) updates for some software features (Like Chord Looper for Genos) throught Musicsoft.
Just skip when you find this post is too 'scifi'
i doubt that they will charge for such an upgrade, it will devide te genos user base in half functionality wise, if they charge for updates. It's more likely that they won't release such features and reserve it for a future model if they want to make money out of it.
But the competition (korg) gives everything away for free, updates, new features and even style packs, the latest style pack vol. 37 which was released this week is insane, it's on a programming level that i never heard on any keyboard. And people do compare brands with eachother (luckely for us users, that there is competition)).
Personally i think that in october with the release of the new psr models we will get a version 2.0 for the genos. And it will be free of charge, it's highly unlikely that the yamaha flagship model genos will have less features than their mid range keyboards.
