Th site is, of course, displayed in Japanese. At the same time, the Twitter account for the series was updated with the following message.
Which was translated by Gematsu and states the following:
The Shin Megami Tensei series 25th anniversary project has begun! A special site has been opened. We’ve also renewed this account for the 25th anniversary! Please look forward to more updates. Everyone, please take care of us in 2017!
So far, no one really knows what Atlus has in store for Shin Megami Tensei fans. Some have speculated that the fifth entry in the series is coming. While others have said that, due to the long dates between publications of the series, it is unlikely that Atlus is releasing a completely new entry. A new, remastered version of the first two games? That's what a large sum of players are actually waiting for. There's no way of knowing, but it is important to note that Atlus is at least doing something with the series, considering its efforts could go to other of their most prominent series. Then again, most of their other popular sagas branch out, or take inspiration, from Shin Megami Tensei.
Shin Megami Tensei IV: Apocalypse, is the last game in the series released by Atlus. It is set in the same universe as Shin Megami Tensei IV, released in July 2013 for North America, and was released on September 2016 for the US. The game features all the characteristics of the Shin Megami Tensei series. The development team, Team Maniacs (also the makers of Shin Megami Tensei IV), set out to make a completely new game for the 3DS, instead of a re-release, something rather usual in Atlus. They wanted to make a game that made everything clear for the story of Shin Megami Tensei four, that is why the game is called, in Japan, Shin Megami Tensei IV: Final.
The team wanted to make the best 3DS RPG, and it shows, since it was incredibly well received worldwide, especially in Japan where, in its first week, sold half the amount of copies of Shin Megami Tensei IV. That number sound lacking, but for a non-numerical Shin Megami Tensei that sum is pretty strong. The game also did very well with reviewers.
