Also, quick pro tip for anybody wanting to keep up with developing ASW games in the Japanese arcades: Use the guild sites.

Great way to keep up with character usage and how characters are doing, along with seeing which notable players are playing. Some of the names I'm seeing playing Xrd are pretty interesting.
The Narukami thing is actually pretty funny. They took away his 5D oki (he was the best character in Vanilla even without it) and gave him like a million tools to make up for it. He's a lot more interesting and looks way more fun, he's just also the god. Teddie is like right behind him, with Mits/Aigis/SLab being really strong too.
