Didn't see a thread for Chapter 4, but Chapter 5 just got announced as well.

On today’s Lionsgate earnings call, the studio’s CEO John Feltheimer said, “We’re also busy preparing scripts for the next two installments of our John Wick action franchise, with John Wick 4 slated to hit theatres Memorial Day weekend 2022. We hope to shoot both John Wick 4 & 5 back to back when Keanu becomes available early next year.”
