There is no official confirmation of Rambo 6: New Blood being in development. A fan-made trailer sparked rumors, but it was created using old footage from The Expendables and previous Rambo films, with no actual new production behind it​។

While Rambo 6 is not officially announced, discussions about expanding the franchise have been ongoing. Sylvester Stallone has previously mentioned the possibility of a Rambo TV series, which could either explore a younger Rambo’s past or introduce a new character taking up his legacy​

Despite some speculative reports suggesting a 2025 release​

no studio or production company has confirmed such plans. If a new Rambo project gets officially announced, it is more likely to be a TV series rather than a film.

Would you like me to keep an eye on any future updates about the Rambo franchise?
