There is nothing that says that Sly Cooper: Thieves in Time is fan-made. Hell, there is no mention of it being non-canon either. Sucker Punch hinted of a Sly 4 being made in inFAMOUS (via an advertisement), and Cole's Amp from inFAMOUS 2 is possible to unlock in Thieves of Time. (They would need permission from Sucker Punch to put the Amp in the game.) As far as I'm concerned, Sucker Punch has given Thieves in Time their blessing and thus count Thieves in Time as canon. Unless Sucker Punch or Sanzaru say otherwise, I will consider Thieves in Time to be an actual, canon part of the series.

Anyway, I do believe there will be a fifth game. Otherwise, there is no point to Thieves in Time ending the way it did.
