That is such a objective, sensible point, and well said to boot. I pride myself on trying to be objective, but you my friend, have mastered it. Much respect!
And I simply keep forgetting about that Amiibo leak, lol. Like

said, I've been losing a little bit of faith in the Dee's chances lately, but it would be folly to forget about the poignancy of that Amiibo data. Why on earth would he have a second Amiibo on file, if not for Smash? I doubt another Kirby series Waddle Dee is coming, so there's only two options: Smash, or it was an error. I'm definitely banking on the former. Add that to his popularity in many polls, and you've got a character just as likely as many of the other top contenders.
I remember the Smash 4 speculation days, and Bdee was only beaten in page/post count by the likes of Ridley and K Rool, and I believe being tied with Isaac. And I'm inclined to consider Smashboards as a pretty accurate sample of the player base at large. Ridley's in. K Rool's pretty much a lock. Isaac unfortunately seems to be dwindling in chance with every Smash release. That just leaves one major pick: Bandana Dee.
Whether this thread slows down or not, that won't change the facts. The Dee is likely. I think, like me, we just forget
how likely, sometimes.
