I appreciate your hard work in finding news and looking for information to find assumptions like this I really appreciate it
but there are a few things that deviate from what i know because what i know is that Satoshi was last active on bitcointalk it was 2010 not 2011.
other than that back to the statement at the beginning. this is your own prediction, it could be right and it could be wrong apart from that, there is still no clarity and it is still a secret until now
