But here's the thing. The MARKET drives manufacturers decisions when it comes to both design, features, and marketing. They look at who buys Arranger keyboards, especially TOTL ones, and guess what; Ol' folks rule. The (old) heart wants what the heart wants and plus, they are the ones most able to afford them. Trust me, the situation didn't get this way by accident.
