I imagine the PA60 as a sort of "PSR" Korg model. It's just a way of selling the same sounds and styles in a cheaper package. Everyone wants cheaper.
The only disturbing ommisions for me would be the "to host" port and the "user insatallable" hard drive option. If they don't happen, I don't think I'd be as excited to switch. I can live without all the rest .... and actually PREFER to.
