The closest we have to a premiere date for Samurai Jack is March of 2017, but that's only because 2016 is coming to a close, as well as that date being tweeted by a member of the production crew for Samurai Jack. That tweet was since deleted and Jason reiterated that no premiere date has been set, but with that being said, that's the closest thing to a premiere date we've got.

March of 2017 does make some sense, though. Not only is it Toonami's 20th anniversary (and a brand new season of Samurai Jack is one hell of a show to celebrate Toonami's anniversary with), but that's when the Mamoru Oshii microseries will be airing as well.
