This is a surprising development. I wonder how successful it will be, though. I mean Sailor Moon was huge in its heyday, but it definitely has not remained relevant or retained its popularity in the way that Dragon Ball has, though both were monstrously huge at around the same time. The kids will probably be like, "this is like Pretty Cure!"
I dunno about that... I'm sure a lot of youngins are aware of Sailor Moon and what came before PreCure. If it were the Western generation of kids, maybe but I feel like Japanese kids may know their 'history' better.
And it is a bit of a reboot, it seems.
As for potential success, I think it could do better than the HxH reboot. (which is from Naoko's husbando LOOOL)
