They'll never know until someone makes a product... the market doesn't exist UNTIL you make the product.

AFTER that, you can say based on results and sales, but in all fairness, who makes one? I'm not talking about an arranger biased towards existing US arranger users. You all know how small that market is... I'm talking about something that aims at whatever keyboard players there are, mostly buying WS's and synths at the moment in the US, and leverages the ease of use that arrangers have in spades over their WS brethren.

If anyone has any doubts about how well it COULD work, think about the DJX for a minute. To be honest, the sales on that thing scared the pants off of Yamaha! They killed it ASAP because it was scavenging WS sales! First manufacturer that jumps on THAT bandwagon again is going to find out just how big the US market is...
