“There’s a possibility we could do a fourth season in a couple of years. There’s an idea that takes place 15 years later.
Say we did it four or five years later, it would be a self-contained eight-episode thing. We may still do that, as it takes place during the Bonfire of the Vanities.”
However, the writer assures fans that the show will have closure in the event that the revival gods aren’t so kind:
“This has closure. For the fans, it’s hard to do a good ending. You hate those shows that don’t end because they got yanked. This isn’t that. We debated whether or not this would be an end. Fans will be really satisfied with the end.”
