I would have probably wrote this off as being a coincidence, but then I remembered a 2014 Facebook post by Sanzaru which essentially declared that they did not have any plans to develop Sly 5. Sly Cooper: Thieves in Time wasn't as much of a smash-hit as everyone anticipated, but it has, by far, been Sanzaru's most successful title to date. To willingly not want to capitalize on a follow-up opportunity, especially since they left Thieves in Time open for a sequel, is simply absurd. If they aren't in fact working on a Sly game, it certainly isn't by choice. A far more likely scenario would be that Sucker Punch, wanting a break from Infamous, decided to develop the next installment. 2016 would be the perfect time for a new release as the Sly Cooper Movie is set to hit theaters at some point this year (that said, there has been no news about the movie since 2014, aside from a recent interview with the producer who mentioned that they are still working on it). Again, this is all speculation, but I have a feeling that something is cooking over at Sucker Punch Productions...
