I agree that there are likely to be some differences, mostly relating to the "endgame" of the age and it's relation to the cavern lake, but remember that none of the Prime ages have any real changes, and that there are still plenty of people who haven't ever played POTS, so I don't think Cyan feels the *need* to make major changes (or any changes) to the layout or design of the age, or any of the puzzles that come before the end of the age.
(Yes, that was one sentence, I'm a sucker for clauses, after all)
While I'm sure they won't change things for the sake of making changes, remember that the Prime ages were designed for Live and that the PotS ages were changed initially to support single-player. I wouldn't be surprised if they took out all the changes they've already made, which would of course leave us with a "changed" Er'cana.
