Sorry, I wrote it wrong. I meant, we know that he has Conqueror's Haki and that most of the characters who posses Conqueror's Haki also seem to posses the other types of Haki, but you are right about it not being confirmed that he actually has the other types of Haki, yeah. Orginally Ace died before WB decided that he woud fight against the whole Marineford alone, and I think WB decided to do so, much because of Ace. So if Ace hasn't died I don't really think that WB had decided to fight the Marineford alone.
