Something tells me if there's merch planned it won't actually be announced until Friday at the earliest. Vinyl...seems like the bigger hurdle honestly. I've just assumed most factories/pressing plants are fully backed up until 2023 at this point
I'm thankful that they probably won't go pantone swatches for the green so it will print much nicer; that green is not CMYK friendly at all (and the album cover looks so much better when you remove the illegal green).
I hope they put up CDs and cassettes for preorder on Friday (and maybe a vinyl if we're lucky) with a release date set in like November like they did for BTW 10th anniversary and also the SL and ROM physicals. I see no reason why they wouldn't do that, easy money.
