NIS America may be bundling Atelier and Neptunia games up for PlayStation 3 collections. As seen on Gamestalk, the USK has listings for a Hyperdimension Neptunia Hypercollection for PlayStation 3 and The Arland Trilogy for PlayStation 3.
The Arland Trilogy would probably be a bundle of Atelier Rorona, Atelier Totori, and Atelier Meruru. NIS America published all three of these games before Gust was acquired by Koei Tecmo Games. While Koei Tecmo published all Atelier titles starting with Atelier Ayesha, NIS America could reprint the three Atelier titles they licensed earlier.
The Hyperdimension Neptunia series also changed publishers from NIS America to Idea Factory International who has been releasing the PlayStation Vita remakes. Similar to the Atelier series, NIS America has the rights to Hyperdimension Neptunia, Hyperdimension Neptunia mk2, and Hyperdimension Neptunia Victory. Those three games would probably make up the Hyperdimension Neptunia Hypercollection.
