IA/VT Colorful for PS Vita

Another Vocaloid rhythm game to be released? That should be worth buying in addition to Megpoid: The Music on PSP. Shame that I wasn't able to find that game to buy for the PSP and it's not in the PSN Store either. This one features 60 songs and certain songs in this upcoming game are already in Groove Coaster arcade in which you should be to play before the game is out in July. Project Diva F 2nd is like out-numbered by this probably due to the disappointing number of songs but it seems that the developers don't want to put in the underrated songs like they already did in previous Project Diva games. They surely want the best songs so that people can play them but the problem is that the song list in Project Diva F 2nd doesn't meet the 39-song objective. Speaking of underrated songs, I don't know which songs in IA/VT Colorful are underrated. From the research, certain songs are already available to listen to and the rest are game-exclusive.
This is being produced by the person who produced Senran Kagura series and developed by Marvelous AQL. There will be some DLCs but I don't know if that is going to happen or not.
