Dengeki PlayStation has a more specific release date for Next Hatsne Miku Project Diva. According to some flying get sources, the Vita entry in the Hatsune Miku rhythm series will see release on August 30.

We're not totally sure of the source on this one, so you may want to wait for further confirmation. Sega did previously announce a Summer release time period, so August 30 would be a possibility.
