Vikings: Valhalla
This historical drama is a spin-off of the popular Vikings series. The budget is apparently huge and filming wrapped up already. We can expect the first couple of episodes before the year ends.
Cobra Kai
The "Karate Kid" spinoff saw a ton of success at the beginning of this year. Ralph Macchio reprises his classic character and trains young karate proteges. We can likely expect the fourth season at the end of this year.
