For those who haven't seen it, this is the WDW version with Jack added in.

Although I agree, some characters do now refer to Jack, they're only the ones who directly interact with him in a scene, the drunken barrel pirate talks about him as Jack eavesdrops, and the mayor dunking pirate asks where he is, while Jack is hiding in plain view.
The only real music change is the ship scene where the captain is replaced by Barbossa, but does retain many of the original X Atencio lines in his script, with a few of the movie 'catchphrases' mixed in.
Watching the video back, I think it's a little different to the original, but overall, the general feel of the majority of it is the same, it's just those isolated pockets of Jackness that are more movie than before.
As for the kid in the video who you can hear go "where is Jack Sparrow?", at least in this version he'll get to see him, instead of in our version where you get the parents having to either explain why he isn't there, or just go "I don't know, why isn't he there". It's a sad fact of the times, but the movies have been so popular visitors to the parks who don't know the history find it strange that he isn't in the attraction!
Of course, an easier way to explain it would be to rename the attraction something like "Pirates of the Carribean: The Old Seadog Voyages" so that it becomes clear to riders that the attraction is a pre-Jack experience.
