Premieres sometime in 2025. The new PV is here. Check out the Crunchyroll article for additional information. Synopsis of the source manga from AniList:
Middle school student Izuku Midoriya wants to be a hero more than anything, but he hasn’t got an ounce of power in him. With no chance of ever getting into the prestigious U.A. High School for budding heroes, his life is looking more and more like a dead end. Then an encounter with All Might, the greatest hero of them all, gives him a chance to change his destiny…
I felt the same, they really just ended right in the middle of THE fight.
Season was pretty good though, excluding the end.
