Yeah i'm definitely sure it's going to be released in 2023, since Melanie just recently finalized the script. So filming hasn't even started yet. The album would def be released this year though, most probably september.
Doubt, pre-production takes at most 8 weeks, production usually takes a few months (K-12 took one) and Melanie would have to likely go through the same wait she did with K-12.
I think there's a small chance filming could have already started, but in the end, I also don't think it will be released until the very end of this year or next year. It seems most probable, but I'm glad there's a chance we'll get a March single.
