On the danish Roland G-70 site there are new demo's of the SR-G01 expansion card (specifically made for the G-70). You have to register before you can access the download area and have a listen (the demo's are in zip format), but I think it's worth the while. I was especially blown away by the new electric pianos and drums.
Maybe Roland got it right, this time.
