George,
Just a wild (and hopeful) guess that it will make a Stateside appearance. Roland's GW-7 (its Chinese name is "Great Wall 7", named after the 7 original kingdoms that comprise modern China), was originally released for the Chinese market and eventually sold worldwide. Hopefully, Roland realizes that global music is pretty damn popular here in the US and will start expanding their offerings. The GW-7 is a decent product and the EXR-40 sounds like it has possibilities also and is more like a traditional arranger with onboard amplification. Keeping my fingers crossed!
