Wano wasnt rushed to promote the Red movie.
Oda simply didnt know what else to do with the fucking arc and wanted to move on.
Unfortunately, as the past volume has shown, he doesnt know what to make of Egghead either, dragging shit out pointlessly.
I almost expect Shaka's face to be shown 3 SBS from now and to have no relationship to anything in universe, just some other movie reference and some poorly written gag about how he's too handsome to show himself around Lilith and the other dorky Vega chick.
