Rambo V Announced!! With Sly Returning

What awesome news to wake up to. It has been announced that Sylvester Stallone will start to film Rambo V in September of this year. The synopsis is
In the new film, John Rambo finds himself in a ranch in Arizona, deeply troubled and wrestling with PTSD as he picks up casual work wherever he can. When long-time family friend and estate manager Maria informs Rambo that her grand-daughter has gone missing after crossing into Mexico for a party, he sets off with her to find the youngster.
What ensues is a violent descent into hell as Rambo uncovers a sex-trafficking ring. He teams up with a journalist whose half-sister has also been kidnapped and must deploy all his skills to save the girls and bring down a vicious crime lord.
Sounds like Rambo does taken. Which I am not complaining about, as Rambo is an awesome killing machine!!
Production is due to start September 1st. I wonder if this pushes The Expendables 4 production back or cancels it all together… More as we hear it guys!!
