Sorry, but if Roland Arranger were that healthy, worldwide, why no new TOTL or MOTL models for YEARS?
G70, E80, E60/50... G70 and E80 are discontinued (although no-one has definitively confirmed that they are discontinued in Europe, too), who knows how long the E50/60 will continue?
And the Prelude and GW-8 (as hard as Roland try to badge it as a WS, the GW-8 is pure arranger) as the only new arrangers in four years or so.... Hardly confidence inspiring, if there IS a healthy arranger market abroad...
