The future CPU parts are easy to figure out. The difficultly is what to do for the GPU. Calling a notebook a "pro" with intel's awful integrated GPU would be a joke.
The key is Nvidia's new switchable
Optimus 40nm 40 "CUDA core" GPU that I think loses its NDA
this upcoming week - Feb 8-12 - based on a well placed source. For comparison, the 9400M only has 16 "CUDA cores". It will be designed to use as little power as possible, especially when the Intel GPU is suitable for 2D use like internet and video decoding, so it doesn't have a huge impact on battery life.
