Yup. Memory sticks are the new tape (in the volatile storage hierarchy). Definitely potential for (re-)proliferation of NUMA optimizations.

The questions are whether G/CPUs have:

- multiple or single SKUs for on-package RAM capacities

- addon RAM ability via sticks, sockets and/or surface-mount

I assume there will be multiple SKUs for on-package RAM capacities. Neither Intel or AMD has ever had qualms about adding more SKUs to their lineup.

It would come as no surprise if addon RAM became a feature of the higher end CPUs (e.g. i7, Xeon, Phenom, whatever)
