The impressive BK-7m module is supposedly based on development work that was intended for an E-80 successor that never happened. Roland had protracted industrial relations issues with workers in the Italian factory which I know caused a possibly fatal delay in the transfer of arranger production from Italy to China (google it if your Italian's up to it). But if they're honest, Roland would admit their heart hasn't been in arrangers since the E-80/G-70.
You're right, with Technics gone and Roland soon to follow, we're all impoverished — competition is the best driver of innovation. Always has been.
