After visiting cybermidi, all I found were SMFs. No styles. And nothing model specific... just generic GM SMFs.

As most of the E80/G70 sales are in Europe, most of the styles from users are coming from there, too. So back to square one. I still feel that unless Roland themselves make deliberate inroads into US styles, it won't matter a bit what 'features' their hardware has. Unless musically they address US players, they are going to paint themselves into a corner, with just older players playing older styles. Not exactly how you would go about building a market....
