Some things I learnt from watching the promotional event (restricted to Japan it seems) at Anime Japan. Do correct me if it seems I misunderstood or misremembered some parts of the interview:

• The production crew is making the distinction between the earlier adaptation and the remake by referring to them as 平成版 (Heisei-era version) or 令和版 (Reiwa-era version).

• Koshimizu Ami mentions everyone from novel-only, Heisei-era, to now Reiwa-era enjoyers to find pleasure in the versions they like, without trying to compare which versions are superior.

• Koshimizu Ami expresses that she feels the years in the industry, and just gaining more life experience itself, will allow her to portray a Holo with more maturity with just the right balance of childishness.

• Nakahara Mai is replaying Norah with the idea that this is a different Norah from a different work.
