While its English name still remains a big question, it turns out that the Neptunia series will not end with Hyperdimension Neptunia Victory – with Compile Heart this week confirming their planned release of God Dimension Idol Neptune PP (One of a couple of names being tossed around).
At the moment there is very little information available other than their development plans, however keep checking back over the next few months for hopefully information on a planned console (PS3, PSV, PSP, PS4), release date and more. The change in Japanese title does indicate something a bit different in the works from the usual JRPG genre…. perhaps a rhythm game?
