Sound is probably the most basic of reasons why we buy...new features are great, but we can do workarounds regarding the lack of them...sound, however, has to be great to begin with.

I think the Korg has really added some great features, and, at least on paper (or specs), it appears the sound is also improved....but, as you say, hearing it and playing it in person will be the deciding factor for those who want excellent sound as the most important feature.

Not being a vocalist, I rely on useful and very playable sounds for my gigs.
