I feel like the final commercial will air right after the show.
It'll have the original teaser we got, with ANTI instrumentals and her laughing. They'll show interchanging clips from R2/R3/R4/etc. with corresponding music from those eras. At the end it slows down at R8. The screen goes black and a new bop from ANTi starts playing (the title will be in the corner) as it rattles off information: Release date, pre-order info, tour pre-sale, where the music will be available. Then it rewinds to the beginning and we're back at R1, accept this time it's not just the piano, it's the actual song which will be on the album (the title will be in the corner).
At least that's what I would do
This would slay my existence be ha manager please and omg that new commercial that just aired rn Illuminateas
