He pointed out Chrom wasn't in and Lucina was several days before the last newcomer vid was available to watch. That's a bold prediction at the time and he was spot on. He also lists stages, which most don't, and he has Ridley and K Rool in, along with Mewtwo, It would make a lot of people happy.
And yet he still missed Robin... I'm not sure how that's possible. We should take all leaks with a grain of salt. If Dixie and Isaac were also playable, that leak would be perfect, I just doubt it. Even without Dixie and Isaac its still quite good, where is Bandana Dee on it, though? I don't see it.
Either way, Robin basically disconfirmed every leak to date, even the most legitimate leak, Gematsu. They've all been utterly annihilated because either they listed Chrom (who was never playable), or they missed Robin, who was.
Either way, I look forward to seeing what transpires. I fully believe Mewtwo, K. Rool, Ridley, and Shulk are playable anyway, and I believe Isaac is right behind them.
