Looks cute enough I suppose and I'll likely check it out, but I don't really understand why after all this time, when a Usagi animated series actually happens, they make it his descendant and not the original Usagi himself.
Only thing I can take a guess at is that maybe it opens the door to going other directions without stepping on the toes of Stan Sakai and his original Usagi? Though giving him all the same friends, or friends who all somehow happen to be named after their own ancestors, makes it more confusing...

edit: If they were their family names that would make sense, but I think those are all their first names? (Or what we'd call first.)
Or we can just go with a conspiracy that it's a way to snub the Turtles and not have them on for guest appearances after Usagi has been invited in so often in their shows. lol (Though I won't be surprised if there is at least an Easter egg nod. And shame on them if there isn't one.)
