no one should be disappointed with the new keyboard:
1. the begginers have a nice start
2. for middle players, this could be a new add or a nice main keyboard for their needs
3. the advanced players have a good hope/preview for the next G series.


as for the variety of the styles, roland already released the exr-e2 keyboard a while ago, which is exclusively loaded with east-european styles (romanian, hungarian, serbian, balcans) so i believe it is possible they want to have the same aproach on the new GW.
