Their back catalog sells very well so by 2023 those numbers I mentioned will be achievable
I see em releasing a single album in 2022 that could potentially sell 1M alone...
Reason why I don't think an album will happen in 2022 is due to touring resuming, YG is itching for that 150M USD world tour BP will surely bring lol
I think, based on the various acts' release history in YG, YG would release a BP album (probably a mini though) just before the tour, or at the very least in the middle of the tour between legs (so they can more easily repeat venues multiple times again). It's more rare in YG to have a tour without a new album to go with it. I do think 2022 will be focused more on their tour than whatever they release physically, but I still believe they will have one.
