I'll translate some pieces talked about here. Spoilers for the franchise, but no specific details mentioned.
- They initially wanted to remake/reboot 1 with a changed story, but realized that 1 is too integral to the setting of Danganronpa, and dropped that idea in favor of 2 due to its setting.
- The alternate scenario is described as happening concurrently with original DR2, rather than as a branching path. (?, might be misinterpreting this)
- In this alternate scenario, all the events of the franchise's story that happened before this are canon. But when asked if this means Danganronpa 3: The Anime doesn't happen, he merely says "Look forward to how this new story ends."
- All the VAs are returning, re-recording all their old lines as well as in the alternate story (except for Monokuma's and Monomi's JPN VAs as they passed away).
- "Stay tuned for updates" in regards to if the old bonus modes will be returning or if they made any significant gameplay changes.
- On the 15th Anniversary of the franchise (November 2025) they will reveal a first demo of the game. Assuming this means a general demonstration and not a playable public demo.
