This is at least the second attempt to make VTMB2. The original version by Hardsuit Labs was entirely scrapped and restarted at The Chinese Room.
I spoke to the new devs at PAX last year and they said they were only reusing assets from the Hardsuit Labs version and otherwise completely making a new game from scratch.
This new version has only been publicly announced since late 2023, although it probably started development sometime in late 2021/early 2022.
