Actually, they are out. American Musical (I think) is taking orders for them and they will be shipping next month according to Behringer.
One thing i'm not crazy about is the limited number of inputs on the main controller. I'd want to expand past 4 inputs (2 of which are stereo with only one fader) and add on to get at least a good 8 channel controller.
As for the function, I think it will definitely find alot of use for the solo track recording studio.
