Yeah its doubt full, but not out of the question, if this new Predator is green lit and goes into production asap then goes through a lengthy post-production the film could be out for a summer 2017 release while Alien: Covenant comes out later in November assuming of course they don't change the release date of that film again.
I'm sure Fox would rather keep their current Alien and Predator brands in separate release dates, partly so they don't collide having top compete against each other, and also probably not wanting to remind people of the previous cross over attempts and stir up conspiracy of a new AVP film with continuing cinematic universe Alien, Predator tie in film, we the fans are aware that isn't the case however a percent of the general public who don't follow movie news up date could presume other wise.
Fox is prepping their War Of The Planet Of The Apes for a summer 2017 release, seeing as those films have been successful that's a safe bet for them, though they've suffered a blow from the Fantastic Four reboot that flopped to the effect where they've removed the sequel from the intended release date, perhaps even cancel it all together starting from scratch.
What is such a missed opportunity is Neill Blomkamps film, put aside the feelings of it being a glorified fanfic wet dream, the timing was so wrong place wrong time, Ridley Scott was busy on other Projects, Neill has the positive response of the fans convince Fox to green light his movie, Scott immediately insists he's still in charge of the franchises course even though he's taken his f**king sweet time on other movies while we endlessly wait, seriously Alien Covenant will be out 5 years after Prometheus
Neill has his project shelved and is either going to wait to Scott is either completing his prequel series, or getting involved with other projects never returning to his Alien film. had the timing of been different and had Scott not been so quick to push his movie first, Neill could have put aside Chappie, come back to it later, present his Alien film in 2014, film this year 2015, completed for a release in 2016 coinciding with the 30th Anniversary of James Cameron's Aliens. A sequel that follows in the vein of Aliens brought to a release date that matches with its 30 year celebration.
Though a percent of the films are either lenient or straight up hate what Blomkamp wants to do with his movie. I'm just saying its a missed opportunity they're not taking advantage of this. Alien Covenant will be out and Alien Resurrection would've had its 20th Anniversary. That's not really something to celebrate, the least respected sequel in this series will be 20 years old and it been dead in the water ever since only able to escape with through AVP, Prometheus, all installments that have been made after are set in the past and never move on forward, Alien 5 could hold potential but really it comes across as a too little too late sequel to a film that wasn't well received albeit a few fans enjoy it. Alien 5 seems impossible by now.Blomkamp's film may either never see the light or day or it won't, who knows.
