Even though the PS3 version of Hatsune Miku: Project Diva F was released in the western countries of the world, the PS Vita version Project Diva f, which a lot of people wanted, was not released. But this changes now, since they announced to bring the Hatsune Miku: Project Diva f game to the European and north American PSN store. This time with an official release date and release price.
The translated version of Hatsune Miku: Project Diva f will be released on March 4th, 2014 in the north American PSN store and March 12th, 2014 in the European PSN stores. It will cost 29,99$ / 29,99€ (most likely – because $=€, there is obviously no such thing as an euro/dollar currency exchange rate), and seems to be ‘digital only’.
It would be a lot better to have the choice between buying a physical and a digital copy, but a digital copy is better than no game at all (It is not confirmed if it is digital only, but there were only reports of it hitting the PSN store, nothing was said about any physical version of the game).
The game was released as a digital and physical version in Asia and the successor Project Diva F/f 2nd will be released at the end of march for the PS3 and PS Vita (at least in japan).
Currently there are no plans of a western version of the Diva 2nd game, but since they’ve ported the 1st one, they might port the second one as well.
