Koei Tecmo delayed Ciel nosurge DX and Ar nosurge DX until March 4, 2021. Originally scheduled to release on January 28, 2021 for the PlayStation 4, Nintendo Switch, and PC, General Producer Akira Tsuchiya released a statement through the official website revealing the new release date. It detailed why the release dates for both of the games were pushed back. [Thanks, Famitsu!]
The official statement mentioned that Koei Tecmo delayed both Ciel nosurge DX and Ar nosurge DX in order to improve the quality of the finished product. Tsuchiya apologized for the delay and inconvenience this may have caused, but ultimately decided to postpone the release date. He went on to say that the team wants to create the best quality experience and thanked consumers for their understanding.
In early November 2020, gameplay footage was released during a Koei Tecmo broadcast. This featured a segment that showcased how players would communicate with Ion. It was confirmed that the remasters would not feature touch screen support during that segment.
Ciel nosurge DX and Ar nosurge DX will release for the PlayStation 4, Nintendo Switch, and PC via Steam in Japan on March 4, 2021.
