Interesting news. Seems it'll be a side-story focusing on Don Kenouji, lol could be fun.
Personally I see this as good news because if Viz brings this over and it sells ... who knows maybe Yen or someone well attempt to bring the Baccano or Durarara LN's as well. (Yeah, i'm probably being overly optimistic, but oh well.)
anyway, interesting news non the less.
