I haven't seen DBSuper yet but the concept of Black and Zamasu is very cool. It might use sprites of other GokuZ but what the screenshots show is that there is a lot more.

I see Zamasu appears in some screenshots but is missing in some others. I wonder if his help would be achievable by command or by power bar.

In any case, it is a great announcement. You guys are a great team and HDBZ will be totally awesome.
