I think you're right about 1.5TB and 750GB hard drives; I'm revising my specu specs to those. I don't think the 3.2GHz Core i5-650 makes sense for the base proc, since it's more expensive than the i3-550, the difference is not very significant, and it would make it (slightly) harder to upsell to higher models/BTOs.
I don't think 320M graphics can be used with the i3 or i5; I'm suggesting the G210 as a possibility. Or possibly just Intel GMA HD. Or the ATI Radeon HD 4350. Or
maybe the 4670, for which they already have drivers. They will have to deal with Intel's prohibition of NVIDIA integrated graphics sometime, even if for the MacBooks, but Hellhammah has a point that they may stick with the C2Ds for now—Steve Jobs said they prefer faster graphics and lower power than 10-20% faster CPUs:
