Kuro releases in Japan this year, there's no western release announced yet and it won't be for 3 years at this rate.
the only gatekeeping is to make sure all platforms release at the same time. there's no way three major kiseki games hit in roughly a year of each other if they weren't being worked on all at once.
depending on the original platforms and development timeline, i'd expect kuro in 2024 and as long as it's not a ridiculously complex script, something like ys x to come out in 2023 or 2024 as well.
Why do they need to release at the same time, though? If the PS4 localization work is done and the game is ready to be released why make people wait? They haven't had any problems doing this up until now and all it does is annoy people who were never planning to play the game on Switch/PC in the first place.
