I am in complete agreement with you, software is far from free and I further agree with you that keeping a price/performance separation between the Bartok and the Rossini makes perfect sense.
Thank you for your mention that Bartok is very close to Rossini 1.x, this gives some indication of what % of the performance is HW vs SW.
The way I read this is that a Bartok today would be close to a Rossini of yesterday (1.x), and that when Rossini 2.0 is replaced either by new SW or revised HW, the Bartok platform is likely to move to Bartok 2.0, the performance of which would be close to Rossini 2.0. However, this move is likely years away but should give reassurance to Bartok buyers in the longevity of the platform.
Thank you for your reply.
