What do you mean by 'VA's power'?

You mean the sounds, or the OS?

I'd be cautious about dismissing this quite as quickly as the G70, though. Firstly, there are a LOT of G70 styles, and VA styles, and Korg styles, you name it, already converted for the E60. If what you want to hear isn't in the E60 yet, chances are you can load it. Or is a style that you really like already in it, but you don't like the sound of it? That's where those Makeup Tools come in.

And come on... be fair. You are comparing a $2800 arranger with a sub-$2000 (probably MUCH sub!) one. One would feel very poorly for the Korg if it DIDN'T sound a damn sight better!
