At present, we only know that September has brought new critters to catch and resources to gather, we do not know the opposite content, we will only wait. But we got two pieces of summer DLC. It's unclear whether the content of the upcoming autumn edition is going to be split, but it's very likely.

In the pre-release Animal Crossing Direct, Nintendo announced a seasonal update, featuring Jack and Franklin, remarking that their respective holidays are close to entering New Horizons. Jack is that the arbiter of Halloween, and Franklin is at the helm of Animal Crossing's Thanksgiving equivalent, the Harvest Festival. thanks to the way summer content is released, Nintendo is probably going to adopt an equivalent approach within the fall update. we will see that the October update featuring Jack and therefore the November update adds Franklin.
