bkilian from Beyond. (ex Microsoft employee) regarding the jump from 8gb to 12 gb instead of up to 16gb.

Actually, it wouldn't. It currently uses 16 4Gb chips. I saw an announcement go past just the other day announcing 6Gb chip manufacturing for DDR3. 16 6Gb chips == 12GB RAM.

And if they split it 8/4, then their marketing materials wouldn't have to change at all. It would have 8GB, for games.

Like I said before, I'm still expecting 8GB, as announced, and as planned when I was there. But expecting something and _knowing_ something are two different things.

A 8/4 means you have hald of the bus width (128bits) acessing 8GB memory and other half (128bits) accesing 4GB... the concurrence to use the 8GB memory will be bigger than use 4GB... there will be performance issues with the 68GB/s bandwidth unless you make a really good memory management with the software.

Works but it is not the best way to use the bus width.

16GB fits better than 12GB.

There is a reason to Dual, Triple, Quad-channel in PC require memory with the same size ... 12GB means a Dual-channel with two chips of memory but one with 4GB and nother with 8GB.
