It's merely an idea that Stallone is kicking around and is keenly trying to convince Russell to agree to at the moment but apparently Sly is eyeballing making a belated sequel to the cops action film. Given we live in an era of Coming to America 2, Ghostbusters III, Triplets etc and Stallone has form on bringing back old characters for successful revisits it's one that's good fun to speculate on happening.
