Intel is staring to sell 512k Banias as Mobile celerons , I suspect this will be very good for GM.
Sure. It is the very same production model as for Pentium 4. But this architecture does not yield performance-CPUs for High-End Desktops, so it can only used for Mobile-segment (and for blade-serverspace, but only for uniprocessor as the architecture is not multiprocessor-capable afaik).
