Let’s be honest here, they’re just saving the idea of GGxBB in Rev’s engine as a precursor to Blazblue’s sequel. They’re just too busy with DBFZ now.
I mean, Cross Tag does look like a last hurrah to ASW 2D depending on how you look at it. Everyone and their mother (including the fetus) in a massive tag battle?
Don’t get me wrong, maybe they’ll do another 2D game, but people have been asking for BB to get the Xrd treatment for a while now, and when Namco asks for it in a DBZ game, you know it’s good and popular.
