For me it is maybe a positive thing that not too much is used from the movies. In this way it could become a more general Pirates theme that can stand the test of time better than just something heavily leaning on the POTC theme.
I think of it like this: younger people nowadays do not know much about Elvira or what it stands for. That may be also true for younger people in several years regarding POTC. But they all will know pirates, just as they will know knights and dragons.
Also this frees the creative people at JJP to make it the best pirates theme they can and seeing what they did with previous games I am sure that I will not be dissapointed.
Having said that, I do feel that the title would be great to be in there, just because it is so awesome and really fits the pirate theme and it is timeless. No doubt however that David Thiel will do an amazing job with or without it.
