As of yet, no Hyperdimension Neptunia game has come out for PlayStation 4. The upcoming mainline entry in the series, Hyperdimension Neptunia Victory II, is however a PlayStation 4-only release. With it being on a sequel on a new platform, it would make sense for Compile Heart to bring the older games to the same console for potential new fans.
Another title, “The Arland Trilogy,” was also rated for PlayStation 3. Given its name, we can safely assume this is a collection including Atelier Rorona (likely the Plus version), Atelier Totori, and Atelier Meruru, as they make up the Arland sub-series of Atelier PlayStation 3 games.
As both titles were rated under the publishing arm of NIS America, we’ve contacted the company for comment.
Update: The USK has updated their listing for Hyperdimension Neptunia Hypercollection. It now lists PlayStation 3 as the platform. It seems its initial listing as PlayStation 4 was an error.
