According to Maaya Sakamoto, there might not be any new Evangelion content for a while. For reference, Sakamoto voices Mari in the Rebuild of Evangelion movies. While recording bonuses for the physical Blu-Ray version of Evangelion 3.0+1.11, she had the chance to converse with Hideaki Anno, the director of the movie. He told her that she was at the final recording for the foreseeable future. [Thanks, ryokutya2089!]
This information comes from the April 2023 issue of the Newtype magazine. Anno was present when the cast recorded bonus materials for Evangelion 3.0+1.11 and was the one who directed them. Sometime during recording, Sakamoto asked him if this was the last time that they would be recording. However, since Sakamoto is not directly involved with the production of Evangelion, she is not entirely sure about the future of the franchise.
Evangelion 3.0+1.11 Thrice Upon a Time came out in 2021 and is the final film of the Rebuild of Evangelion movie series. The Blu-Ray and DVD for the film came out in early March 2023, about two years after the theatrical release. Rebuild of Evangelion retells the Neon Genesis Evangelion story but in an alternate continuity than the original. Therefore, it has a different ending and the characters are somewhat different from their TV counterparts.
Rebuild of Evangelion 3.0+1.11 is available on Blu-Ray and DVD in Japan. It is streaming on Amazon.
