I think clusters are going to start getting much smaller ...
..or much "larger" (in number of CPUs/cores)... now you can have 8 cores per CPU where you used to only be able 1.
You can never have too much computational power.

Yes, there will be many more cores, but I suspect that the cluster programming model will start applying to smaller and smaller systems.
I can imagine a system where each CPU die has multiple cores with on a chip with memory, and multi-CPU machines appear to software as a cluster rather than a single system image.
