King writing final episode with new material

Just saw this post on IndieWire... Evidently SK is going to extend the story with a coda that evidently takes the story past where it ended in the book. I'm guessing it will probably also include the fate of Flagg similar to how the extended edition closed:

"For one of its biggest upcoming projects, CBS All Access is enlisting the services of one of the only people who could help add another chapter: This adaptation of “The Stand” will feature a new ending written by the book’s original author Stephen King.

The streaming service’s EVP of Original Content Julie McNamara told reporters at the Television Critics Association summer press tour that King’s contribution will be a special close to the series’ story, new and different from the source material of his iconic 1978 novel.

“For fans of the book who wondered what became of the survivors of ‘The Stand,’ this episode will contain stories taking them beyond the book,” McNamara said, confirming that production on the series will begin this fall in Vancouver."
