While this is not by any means a proper confirmation, at least this is coming from an official twitter account, and if this starts spreading around and there's some sort of false information, it'll get taken down. As I said before, I flip flop on the idea whether it'll be exclusive or not. I wouldn't be surprised either way, but in the past, marketing deals with activision have never led to the websites for their games only having a specific platforms logo only. And Sony approaching Activision for this and saying this is done in a partnership would lead me to believe this is an exclusive.
