On IGN's uncomfirmed character list they have added any Assassins Creed's Connor to the mix go check it out, take this with a grain of salt as the page could be edited by anybody and the rumor is from Paul Gale
It's fake because Superbot confirmed that there are only 20 characters in the game.
Omar confirmed 20 launch characters. Please tell me how that definitely means that there are only 20 characters in PSAS, and that "launch characters" can't mean anything other than what you think it means.
Don't assume anything just because misconstruing words makes your opinion seem more valid.
