where is the proof that Izuna didn't have a susano'o though? All we saw is tobirama using flying rajin on him. It's hard to tell if kishi was speaking through sasuke or if it was just sasuke's theory that the double mangeyko automatically grants susano'o. Sasuke isn't exactly the best source of info, at the start of the series he didn't even know who madara is, didn't know about izanagi/izanami, so I understand why one might be skeptical of sasuke as a source. Itachi would be a better source to confirm the the abilities and workings of the sharingan. susano'o awakens according to one's emotions, so that isn't indicative that sasuke knows how his susano'o came to be. He was destined to awaken it.
