Fudzilla this morning is reporting that Nvidia has told him directly they wont be making DMI-based chipsets for Clarkedale and Arrandale CPUs. It appears that Charlie was right, at least partially. In the face of Apple not using their chipsets for Arrandale and the legal battle with Intel over their right to make a DMI chipset, Nvidia may have decided that it wasn't worth it to fight a legal battle if they didn't have a tier 1 OEM to sell them through. Its still be seen if Apple switches to ATI-based GPUs for the laptops. This means that the Arrandale-based MBPs in Q1 2010 will have the Intel chipset and probably GPU for the lower end MacBook Pros. Of course the higher dollar MBPs will have discrete graphics, but I don't think its worth it to put a slow GPU (GF210M - 14W TDP) to only be twice as fast as the Arrandale GPU when you factor in decreased battery life standpoint (unless Apple figures out how to make it fully switchable so you can just switch between the Arrandale GPU and the 210M without them both being on and consuming energy at the same time). The 240M is about 5x the Arrandale GPU performance at 23W TDP so that will definitely go in the higher end MBPs.
