The spinoff is Ballerina with Ana de Armas, latest update on Wikipedia is:JW5 is confirmed and I think they're doing some spin offs as well.
The latest I've read on John Wick 5 is it isn't even close, no release date, no director, no cast. The gold standard for John Wick movies for me was the first one, the rest have not held my interest anywhere near the same way with the first one did.Initially scheduled to commence in summer 2022,[4] principal photography officially began on November 7, 2022, in Prague, Czech Republic.[23][11][24] Ballerina was in post-production in February 2023.[25] In February 2024, producer Chad Stahelski was working on additional action sequences for the film with director Len Wiseman.[26]
The more I look at these videos the more I think the Pro could be a real winner. Excited to see one in the wild for sure.
