Bell Media announced that the sixth season of POWER will premiere exclusively on STARZ in Canada, which explains why the series suddenly disappeared from Super Channel. Normally, the Power contract would be for "life of series", but there may have been a clause allowing Starz to take back the rights, or Bell Media may have bought them from SC.
Deep State Season 2 has now been scheduled for August 25 at 9 PM ET on Fuse. Available On Demand Aug 26 2019 to Feb 28 2021.
American Gods Season 2 isn't on the August schedule.
SC replied in the comments section of Harlots that they will be showing Season 3 sometime this fall, no confirmed date yet.
