There is a high chance that the 4 small slots are the dlc...
Small chance that it could be Hwang, Liz, Rock or Cassandra. They seems to be cut in the end. We might see them in the story.
Can't imagine a game without a Hwang/Yunsung style for since 2 game... And showing dlc slots already since 4 month would be lame. But like I said, Namco can do anything, especially the worst :'(
Still waiting the game, but I lost half of my motivation for that game.
I'am happy to have founded Raphael, I hope Raphaels main will remember Yunseong/Hwang.
