First off, there should be new Blu-ray releases of the 1st-3rd "Austin Powers" movies that, in addition to including all of the previous bonus content from all of the previous home video releases of the films, include extended cuts of the films.

"Austin Powers 4" should pick up shortly after the events of "Austin Powers 3: Goldmember", with digital de-aging being used. The film should be at least 2 hours & 24 minutes long(without counting the opening & closing production logo sequences and the opening & closing credits sequences).

There should be an HBO Max original animated "Austin Powers" prequel TV series that takes place in the 1960s, and is titled "The Groovy 1960s Adventures of Austin Powers". The intro sequence for this TV series should use the song "Austin Powers"(performed by the Wondermints).
