Well, Minecon was...uninteresting, but at least it had footage of pandas at the end, so that's a plus?
I remain of the mindset that it would be really strange for Nintendo and Microsoft to be partnering to put Minecraft content into Smash and then not even hint at it during what is, as I understand, the biggest Minecraft event of the year. Wouldn't the entire point of such cross-promotion be to get Minecraft players talking about and eventually buying Smash? Maybe it means nothing, but between this and the surprise Pokemon music track on the blog this past week, I'm excited by the prospect that the leaks may not be correct after all.
