it looks like Bandai Namco is taking full advantage of the 15th Anniversary of The Idolmaster with the announcement of a new game. The company has revealed that they will be announcing a new game in the series, on a livestream, happening on January 20th, 2020. There's no real details beyond that as they're saving everything up for the big reveal. But hey, at least we know what's on the way.
The Idolmaster has over 25 games to the franchise, with several being released in single years. The most recent one being in 2018 with The Idolmaster: Shiny Colors. Considering how close we are to new consoles being released, it does make you wonder if they'll be doing one last hurrah on the current generation or saving for the next one. We'll know more in less than four weeks.
