potential spoilers ahead, but it's all speculation based off New Avengers #27, so that stuff is spoiled ahead most definitely. The popular theory right now is that the new Ronin is Deadpool. However, do y'all buy that? They can't get by his specific speech bubbles which is the most obvious thing conflicting with my vote. However, given that he is an expert with the swords, and also knowing that the costume was designed with a female occupant in mind, I'm thinking that perhaps the new Ronin is....Colleen Wing! I mean, think about it...Ronin says "yo Cage." Deadpool isn't on those kinds of terms with Cage...however Ms. Wing is. She's also wicked deadly with a samurai sword. She also has white text bubbles. She's also cool with Iron Fist. I dunno, I guess I'm just trying hard to find someone other than Deadpool, just in case it ain't him.
