My thoughts are, that the next Friday would be a perfect date for the single and a MV (it presumably being A&W), with additional promotion done until it's out - like it's announcement, boxset being available, singed CDs, OceanBlvd account content uploads etc. and even a snippet of some sorts.
Then after that she does some promo in terms of interviews, photoshoots like the billboard ones and the rumoured live performance on the late night shows.
And she would have enough time to promote the single after it's release and the album's release in March almost 2 whole months with a new single with a MV dropping on the release date of the album, like White Dress did with Chemtrails.
After the relase there could be a tour announcement and then later on one more single with a MV before the tour, that would come most like at the end of 2023 or spring 2024.
I wish something like this happens, but us Lana fans can only dream I guess
