Most people want retro sounds, yet at the same time they want all the modern benefits that help streamline the workflow. You mention touchscreens and menu diving a lot even though good screens make life much easier and even allow for deeper features. DSI makes phenomenal sounding instruments no doubt, but they're way behind in certain areas. Perhaps people want three OLED screens for some reason, though there's certainly better ways to utilize the main OLED screen. My favorite example is, why would you have a thousand preset slots available and no on-board categories? But hey, I know the P12 at least shows the envelop visually, which is a start.
