Well considering Halloween Ends is the end, and
Michael Myers is literally killed at the end in a meat compactor, kinda tough to do a sequel when your main bad guy is donezo! They also killed off the “New Michael”, so there’s no one to take the mantle anymore
As well, the team behind this new trilogy, are not making any future movies. The movie rights is going to be reverted back to one of the producers from the original movie, so there’s still a chance they could make a new movie or trilogy, or even make a tv show with another team.
Also, not sure what you mean by 10 episodes, because there’s never been a show for Halloween, yet.
