I don't think he's traditionally included Echo Fighters with unique fighters when talking about "new characters." With the exception of Richter, the echo fighter announcements have been quick and informal, and the exception of Richter was only because he and Simon arguably echo each other. He only ever said "we have one more fighter to announce" when talking about Richter because of that.In the Japanese Direct Sakurai says there's ONLY a few more participating fighters left to reveal. I was wrong before but I think this also includes echo fighters.
