Yes Sly 4 is real and it is going to be called Sly 4 King of Thieves. It would come out now but Sucker Punch is working on stupidinFAMOUS. No offense for those who like that game but I want Sly 4 to come out already. Sly 4 will come out in 2012 probably but not sure so count on this answer for those who are trying to get the official answer. There is no official answer yet, I'm trying to the official answer to but no one knows for sure. For those who know for sure please make your own question and put the official answer.
