However, the project has either been delayed or cancelled at this point.

A 24th Pokemon movie codenamed Bauer was also in the works, but has seemingly been delayed or cancelled.

As for the games, Pokemon Legends: Z-A has reportedly had its source leaked.

Interestingly, the Switch 2 is also codenamed Ounce.
