The John Wick TV show was announced back in 2017 shortly after the second movie had a great deal of success, both critically and financially.
“The angle they’re working on The Continental TV show right now is a different perspective on the whole world, it’s coming at it from different characters’ points of view and what the breadth of the world is.
Not that John Wick won’t be involved with it, it’s just not from his perspective.”
It had previously been confirmed that The Continental will be a prequel, taking place long before the events of the movies.
