Personally I would rather they concentrate their efforts on updating the PPC frontside bus and creating better reference designs for the north and south bridge.  I for one would love to see a company make reference designs the companies could make chipset's, cpu's, and memory that all ran at the same frequency.  There was a short periosd in time when this did occur.  But ithas long since vanished.  get rid of the bottle necks and bring on Solid-State drives!
