That doesn't make the answer incorrect. They Paramount have renewed SNW for a S5 consisting of 6 episodes. When they film it will be up to the Studio. Paramount OWNS the Canadian studio they film the series in. Whether or not Skydance remains a business partner in it's production doesn't matter.
If the studio wants or needs to it can make a separate deal for Season 5; and yes, if something bad happens they could change their mind and cancel it too.
But in the end, if it's filmed, it will be when Paramount says so.
