As you may know, TGS is next week (18-21 Sep, 20-21 being for public).
There’ll be announcement of NEW Project Diva game. It would most probably be ‘F Extend’ for now (not F 3rd considering it would require new gameplay element).
For Neptune series, not only they’ll reveal more info about Neptune VII for PS4, they will actually announce a NEW Neptune game!
Now, the new Neptune game might be Neptune Re;Birth 3/V (remake of Neptune V for PS3). Or, it could be a spin-off game in the spirits of PP, Noire, U.
PP -> Idol games
Noire -> SRPG
U -> Musou games
New game -> ???
It could be a 2D fighting game… ^^;
Another possibility is rhythm game since the series has amassed quite a number of vocals.
Anyway you can watch all of these in livestreams next week!
