Well my Montage 76 was $4350 AUD so I would expect Genos to be somewhere around there if Yamaha want to make workstation inroads into this makes great sense.
I gotta tell you I think the Montage is the most exciting instrument I have played, and if Genos is anywhere like it with the inclusion of styles etc, this will be very exciting
Montage 6 was exactly €1000 cheaper then Tyros 5-61. So dont expect the Genos to be any cheaper... Montage pricing is comparabale to Motif, Tyros has allways been more expensive
