Quoted from MikeS:
My guess is a new POTC machine based on the new movie that's coming out this Summer. That just fits the kind of machine that Jack likes to do as it's great for the whole family. It's just a hunch based on no evidence but I'm surprised it hasn't been mentioned yet. POTC was an excellent seller for Stern and now that a decade has passed it is probably time to take another crack at it.
This is a worst case scenario in my personal opinion. Making a pin based on a movie series with dwindling popularity and a theme that has been done before. JJP needs a theme that is new to pinball like Toy Story or Harry Potter. Something fresh to get people excited about.
Flash forward to Pinball Expo 2017 and Pirates of the Caribbean is announced. My thoughts would be "it's been done before....by Stern....ho hum....the game might be exciting....they need to one up the sinking ship toy and hope that clips from the movie dazzle people".
