To promote the release of the Digimon Frontier BD-Box that is coming out next year, Tokyo MX will be showing the first episode of the Blu-ray remaster for Digimon Frontier on January 3rd at midnight (Japan time, just as it's becoming January 4th.)

In addition, Animate Times has interviewed Junko Takeuchi (Takuya) about Frontier.

We hope to provide a translation of this if possible.

Pre-orders are available for the Digimon Frontier Blu-ray box. It will be available April 2nd, 2019 for 53,800 yen. Early versions of the box will include a new Frontier audio drama. We've recently gotten various details for the new audio drama which you can find here and here.

Update- Since a few people has asked me...

The image above is not a screenshot from the remaster, we do not expect it to look like that. That is a promotional render that Toei has been using since the show originally aired.

We expect Frontier to look roughly the same as Tamers. We have various screenshots of the Tamers BD-Box in our gallery:

Episode 51 (Final Episode)
