The new Nord will be the Nord Stage 3, according to an out-of-focus 'appetizer' video. It obviously has a well-sized display, which is unusual for Nord.

A rather credible website, which correctly predicted that this model would be revealed in December, says it will cost 4,000$!


Regarding a Roland Fantom successor, I am pessimistic. I think it was Roland's intention to address the less risky low-/mid-priced market with the FA-06/08, and they are economically in a position too unsettled to invest in a high-end workstation. I hope it will change again one day. It would also be very nice if the released a BK-7m successor and didn't completely forget the BK-9, but no sign of that...
