The Styles are really no problem (they are basically interchangeable), it's the World tone presets that are the major difference between the various GW-8 models. With my GW-7 and the Styleworks software I can already use Styles from all the major arrangers and the World sample set is pretty damn good, with instruments from all over the world (not as narrowly focused as the GW-8). I was just hoping that they would have given US consumers a choice between a couple of models at least, as they are doing in Europe. Even though it's not an arranger keyboard, the new Korg M50 is looking mighty interesting!
