Théorie neogaf qui expliquerai que sf5 se passerai bien avant street 3 ces en anglais je préviens:

I dont know if it has been discussed yet, but informations about Udon latest work "The Life and Death(s) of Charlie Nash" have been surfacing lately. Since this comic is part of SF5 advertising and deals with Nash reappearance I think we can safely assume it somewhat follows SF5 story.
Interesting summary from reddit r/Kappa user Twotecks (spoilers for the comic obviously) :

So Charlie has amnesia and is roaming the desert, secretary girl and Urien find him and start telling him about his past when he joined the army, teaming up with Guile, his psycho power, all that shit. Then they tell him he was defeated by Bison (Alpha 3 I think) and became Shadow and told him about all the nasty shit he did as Shadow. It references some of the Udon comics here but also directly goes against it. Eventually it leads to a big two on two battle with Guile and Chun vs Shadow and Bison.
After Guile and Chun free Charlie from the Shadow mind control Charlie does a wake up flash kick taking him and Bison off a cliff. [...]
Then they tell Charlie he died from the fall and that this whole desert is an computer generated illusion and Urien and her consciousness were uploaded into it to talk to Charlie. They wanna recruit him into the Illuminati cause of his personality and psycho power. They give him two options, join us and kill Bison for good or we can erase your memories and alter them and make you join us as a zombie (which they don't want cause apparently Charlie's personality is that cool?). Obviously Charlie says "I'm in" and he wakes up.

As if we needed more proof it seems to confirm that Nash was indeed brought back by the Illuminati, and interesting point, it seems he is not brainwashed and is willingly working with them.
It would also support the rumours that the game is dealing with the fall of Dictator and takes place before SF3.
