Superconsole?

I was talking to my friend at EB Games and apparently Sony wants to make the PS3 upgradeable. I know for a fact that Sony wants to make the PS3 have a 10 year lifespan and that could be possible if it can be upgraded however when coupled with the Linux pre-built on the HDD it raises the question is Sony trying to create a console or some sort of value based Supercomputer?
