The lack of a "sound processor" is not that big a deal. One of the reasons Motorola developed AltiVec was to reduce the number of coprocessors on embedded boards including DSP.
Nintendo has a history of having the most difficult licensing process. This lip service doesn't get a rise out of me. If they were serious about this model, why not open up the current Game Cube platform now?
Just to keep things real :inquisitive:
