Thought they had been saying this was a 2024 show so it feels a little early, but i'll take it as long as the quality is there! I certainly hope the quality is here. This isn't like a lot of the Star Wars or MCU shows where there isn't enough juice there to justify it being a show over a movie (which most MCU shows at the very least feel like they should be). Percy Jackson to me will greatly benefit from being a series I think as, much like a video game adaptation, you can't properly retell a book in a 2 hour movie without leaving a lot out (although the Harry Potter films did a great job).
Two-episode premiere on December 20th (multi-episode premiere's on D+ are starting to become much more common it seems or even binge dropping).
