In a new interview given very recently, Couture reiterates his involvement in a new Expendables movie. He asserts that he has been in the procession of the script and that EX4 is happening. Filming has been pushed to next spring as he had announced in an interview that was previously posted here, and this time he explains that the postponement of the production was due to some scheduling conflicts (Sly’s Samaritan maybe).
Couture seems to be very confident that EX4 is happening and this time he seems to be more informed of the movie’s development and progress. He’s been wrong before but I feel like giving him the benefit of the doubt this time.
