The demo for Hyperdimension Neptunia Victory (Ultra Dimension Neptune V in Japan) can be found in the Japanese PSN store. The game has been out sometime in Japan and its has a NA and EU release date for sometime Spring 2013. Honestly it plays much better than Hyperdimension Neptunia mk2.
Useable characters in the demo are Neptune, Noire, Pururut.
For those that can't find it - http://www.youtube.com/watch?v=3TBuCeeyMrY
That video is kinda useless due to new PSN Store design, if there's enough requests I'll do it with the new store.
