Eri just sent in this report from the Winter NAMM show in Anaheim, California. As you can see in the picture, she's playing an Etherwave Pro with a wooden back. Eri and Pamelia Kurstin performed at NAMM, Eri playing a Disney song medley and Pamelia demonstrating her walking bassline and looping techniques.
There is no word on this yet on the Moog website, but as soon as I learn more, I'll let you know.
