Kurenai and Anko surprised me, but the fact they jumped from those two to Naruto Kyubbi mode was a huge WTF? NO!!! xdLMAO I know right, I wanted to play as Tayuya and pwn everyone with my amazing flute abilities xd (I played the flute in 6th grade so I respect her for using her flute as a weapon U_U)
But, I guess it's good that Anko and Kurenai are most likely playable, because in the scan they were shown in, the angle pretty much suggests they are playable. And the fact that there is no support circle underneath them as well.
So, next up the Sound Four, they really don't need to confirm Danzo and Madara because odds are they are most likely playable.
I don't even get why people are questioning Danzo or Madara. Danzo was in Impact, playable, and he's a major boss in the Kage Summit. Mei and Onoki are playable, Sasuke's Susano'o is in, and the even this Naruto is. Danzo is pratically confirmed.
As for Madara, he's 100% in if you mean Tobi. The question is if he'll be the same in Storm 2, or have say a new moveset or character slot. In Impact, it was 100% Serious Tobi playable. So, I think we'll see Tobi in 100%, but serious is like 91%.
The Sound four should be soon. I need them so badly.
