Donny, maybe in the U.S., but in the rest of the world arrangers are doing well. Ketron and Korg both have amazing new products, not to mention the terrific little module from Roland. It seems as if every accordion player in the world, and many guitar players, are doing one-man things with the BK7m or Audya 4.
And you can count on Yamaha to continue repackaging their arrangers every couple of years as well.
