Well now we are in an interesting situation in that the entire consumer mac line-up has made the switch to NVIDIA motherboards. To me this seems unlikely to change as doing so would be giving up the power of the 9400 and its successors. So with an NVIDIA motherboard (guaranteed?) can anyone then see the next macbook pro's with AMD powered discrete gpu's? I would imagine doing so would be giving up the dual gpu set-up currently found. Would apple really back peddle on the concept so quickly? What is everyone else's take on this? Adam Sidenote: In case anyone else is wondering the recent talk of the latest AMD powered mobile chips got me down this line of thinking.
