FBI: Most Wanted has already received a series commitment from CBS, so it’s likely to happen.
Law & Order showrunner Dick Wolf (who, naturally, created FBI) will co-write the pilot, titled FBI: Most Wanted with longtime Law & Order collaborator Rene Balcer.
The procedural crime drama FBI is already making a big impact on CBS.
CBS has already renewed FBI for another season, so it looks like the characters will be around for a bit either way.
