Quoted from PanzerFreak:
Before anyone actually cancels I would say wait for JJP's response. Why? JJP has proven to us that they listen to customer feedback. With the Hobbit they went through and made a ton of positive changes to the game after first revealing it based on community feedback. Maybe something similar will happen here with POTC.
Let's hope it doesn't go The Hobbit route - tons of delays, revamps, and changes and then a release well after the last movie hit DVD when the promotional impact was gone. I say JJP should take their lumps, code the hell out of what they have left and move on to more profitable, less controversial waters with Toy Story and Willy Wonka.
