I was talking about this on Twitter few days ago.
I'm surprised they haven't announced it yet, the last main entry in the franchise was 7 years ago.
I know the series isn't hot in the west, but I always assumed it did great in the Arcades of Japan, so I was sure it's gonna happen eventually, but I'm becoming slightly concerned now.
That said, this year is the series 20th anniversary, so hopefully something gets announced this year.
Any idea of events happening this year that are a likely place for the game's announcement? Aside from TGS of course.
