I think the c2d will see an update next year...
I prefer the crumar mojo over the c2d..
I have a C2D (and a C1) and a KeyB. The KeyB is far more authentic. The Mojo sounds ok but is PC based and the control surface isn't as close to a real B3 as the KeyB. Also, the C2D costs as much as a Legend and IMO there is no comparison. The C2D needs a sound engine upgrade.
