An advertisement (with audio) on the Japanese Nico Nico Douga video-streaming service has hinted that there will be a new title in the Idolm@ster franchise announced in late March.
From Gematsu: "Bandai Namco has released a 15th anniversary trailer for The Idolmaster series. The series will celebrate its 15th anniversary on July 26, 2020.
According to Bandai Namco, the series’ anniversary period will run from July 2019 to July 2021. In other words, these are the two years in which it will release The Idolmaster 15th anniversary-branded products or have 15th anniversary-themed events."
God Eater 2 has a little crossover with another Namco Bandai series, The Idolm@ster. If you purchase the hunting game from HMV in Japan you’ll get a code that unlocks an Idolm@ster costume for Alisa as a bonus.
SGCafe: ''Namco Bandai Games’s general producer for The Idolm@ster series, Yozo Sakagami, appeared as a special guest on Sega’s Samurai & Dragons Fan Meeting 2013 Summer event in Akihabara held earlier today.''
