Also, (good) animation takes an ungodly amount of time. And seeing as Gendy is all about that visualization, especially in a cartoon with zero dialoge, it's no real surprise.Pandemic maybe. But more likely, because Genndy is Genndy. Took Samurai Jack a decade after all.
Anyway, I'm really glad we're getting one. I just watched the show for the first time recently and that cliffhanger killed me.
