I'd have to agree that most of what's been said by him has been fairy obvious, outside of Incineroar, and the big things that would really cement him as having inside information weren't touched on. He never mentioned Daisy or anything regarding echoes before they were revealed, and never did mention any of the echoes from the Smash direct, only saying Isabelle was one, which was something that many many many people were guessing after echoes were known to be a thing. I'm willing to give the benefit of the doubt that someone could mistake Isabelle for an echo, but, like Ken, its something that a ton of people were predicting. But even so it still turned out to be wrong.
