Not that I'm aware of. The only "revamped" AP is Runelords (with the Anniversary edition), so if it was done in 3.5, it's only in 3.5 (though the folks at Hero Labs do have conversions for the monsters with their datafiles.)
You can see the same thing happen for a lot of the other adventure paths if you compare the covers on paizo to the amazon covers.
As Kadasbrass mentioned Amazon doesn't always update the final covers.
For Example:
So to be clear, when Paizo announces its new books, the covers aren't ready yet, so they make temporary covers using older material. This way they can already make a page for the book and people can already comment on it in the messageboards.
The white cover shows a drawing from one of the Rise of the Runelords books, which was used to build this mock cover for Curse of the Crimson Throne. Webstores like Amazon already put up these covers to offer the book for pre-order. The problem is that they often don't change the cover to the new version, so the temporary one can survive for years, while it was never really printed.
So CotCT was only printed in one version, which was 3.5 and not the Pathfinder rules. Still, they are more or less compatible, and as other posters mentioned here, you can find a lot of conversions and sometimes even new builds for the NPCs on the internet.
If you want to buy this complete AP, you'll find it hard to pick up the second installment "Seven Days to the Grave", as it is sold out and can only be bought secondhand for ridiculous prices. The PDF version will of course always be available here at Paizo for a normal price, so there is a solution.
