My money's on Nick Szabo as the most likely person to be Satoshi or part of the team. Just in terms of the stuff on his blog dating back decades, it's clear that his research led directly to the creation of bitcoin - at the very least, he must have met the people involved.

I have no real interest in the identify of Satoshi though, and only speculate out of idle fun - it would be bad if the identity of Satoshi was proven and made public. His/her/their anonymity is a good thing.
