The only thing I hope is that she gets in over Rex and other Xenoblade character, not really a fan of them, even though I think KOS-MOS chances are slim.The thing that is most worrisome to me at this point is that the DLC 2.0 characters hypothetically don't have the same restrictions as the first batch RE: when their games came out compared to development. That would, in the eyes of many people, mean Rex and Pyra could be selected at this point. While I believe this thread suggests KOS-MOS as a Namco rep as opposed to a Xeno Rep, generally speaking she's both. ((I usually see her as a Monolith Soft Rep, but that's splitting hairs.)) They may not choose to add her any time soon after adding them, or Vice Versa.
Obviously still support KOS-MOS ((She's my top pick, and I'm a huge Fate/Stay Night fan)), but that is something that may become a new hurdle for her.
