A little under a decade since the last Sly Cooper game, it seems like the beloved franchise of anthropomorphic animal thieves is stirring once again - however, by the time we see anything come of this we'll probably have crossed that ten year line since Thieves in Time. According to an insider report, a new Sly Cooper title is in very early development.
The news made the rounds on Twitter initially, with a reputable industry insider who sports a good track record of reporting accurate info spoke about a fifth mainline Sly Cooper game being in development. The insider, Nick Baker, reiterated that the game is very early in development.
Very early in development generally tends to translate to "years away from release, and maybe even official acknowledgement" - GTA fans sure know how that feels - and in the current climate of common game delays you just can't bet on development pipelines anymore. In any case, as Thieves in Time was released in 2013, you can bet that Sly Cooper 5 will launch at least a decade after it.
Thieves in Time had a special secret ending video that players could unlock by completing specific actions throughout the game, and that secret ending itself was a set up for a sequel. Thieves in Time was developed by Sanzaru Games instead of original creators Sucker Punch Productions, as the latter was working on the Infamous franchise at the time.
