#1 theory: Dorian is indeed Satoshi, but playing it off to his amusement, why would someone who worked on classified projects for the U.S Military not have good english skills? The letter he wrote showing his bad english was probably due to him being drunk. He also doesn't want to be in the spotlight, and thus chooses to remain anonymous, although that's gone now.
#2 theory: Dorian is Not Satoshi, Satoshi's p2pfoundation account made an announcement after years of being offline saying," I am not Dorian Nakamoto." The real Satoshi is someone completely different, with Satoshi Nakamot just being a name he made up, to confuse anyone trying to deduce his real identity in the future. He will reveal himself when he feels the time is right.
#3 theory: Satoshi Nakamoto backwards spells otomakan ihsotas which can be translated into Internet Armaggadeon, Satoshi is the the fifth horseman, the Keyboard King, who will bring an end to the internet as we know it.
#4 theory: Satoshi is a a cyborg from the future.
