AFAIK, Bebop, this OS has not been released yet, either in Europe, or in the US (and US releases usually take longer as the lawyers wait for the bugs to get fixed first).

AFAIK, RolandUS STILL do not have V3 for the G70 on their site! Talk about caution...

RolandUS are in disarray at the moment, after the debacle of putting the arranger line lock stock and barrel in the hands of the CK dealers, who did NOT want to carry them. The products are great, but the dealer support has just about dried up.

You MIGHT try to get this from a European dealer when they have it, rather than wait for RolandUS to get their asses in gear...
