Sounds great - top marks to Roland.
All they need to do now is bring out an E81
(or G71). In the case of the E81, it needs to have range topping additions to the Prelude and be reasonably compact & not too heavy.

I like the E80 but it's just too heavy & cumbersome - although I would happily settle for a module version of it. This would be one way for Roland to increase their sales whilst still using the last keyboard's technology.
They could then, using the same chassis, repeat this with every new range topper which they introduce.
