I don't know if this has been pointed out, but looking through Kings Island's website I found "Paramount's" in the Nickelodeon Universe logo under the rides and attractions page. I know nothing major, but just something I noticed.

Oh, there's other inconsistencies there, too....it needs a thorough scrubbing.

I wonder when (if?) the sites will be remodeled to be "consistent with other Cedar Fair parks."

Or is the old Paramount underbones a nostalgia thing?

I would say it will take a while for Cedar Fair to get rid of every little thing that is Paramount. Even the slightest thing.
