The way I look at it is that the DGX is so good in so many areas, why cripple it with an accompaniment engine from the low end PSR instruments?

Ian, the way I look at it is if they put the T4 guts into the DGX-650 they would be competing with the Clavinova series, which would really be dumb. I think that most of the folks that would buy this board want all the features of a great sounding piano more than they want the intricacies of an arranger keyboard.
