Seriously, best thing is if Kubo gave a ton of pointers to what actually happened to the directors. There were still plenty of battles to be had and hopefully they remove the offscreening that started around there.
Five Sternritter, including the guy who took Shunsui's eye, off screened by Byakuya...
Soi Fong vanishes in the final arc...
Gerard Valkyrie being randomly eaten by Yhwach..
It'd be great if Kubo gave the anime team his full notes on how he intended to end the arc. I dunno what their budget will look like, but it'd be a massive let down if Bleach decided to be rigid with canon now of all times.
