To be honest when I first saw the Bill tweet I didn't even think Smash at all.
>Guy makes a tweet about a spooky looking asteroid, comparing it to the MM Moon.
>Bill makes a reference to MM.
Bill's personal twitter is very casual. He'll tweet and respond to things just because he feels like it.
When does this asteroid pass earth? Could it be that THAT'S what Bill meant? As in "Oh **** it passes soon?"
Also where are these people actually believing it's a smash hint? I just see people in this thread commenting on it, and others going "you idiots this isn't a hint" without any people actually saying it is.
As for him hinting at a Big House announcement, I doubt it. EVO was significant because EVERY big fighting game is there, and as such it attracts a lot more viewers. Many of those viewers might not be huge into Smash news, and so an announcement could get them to watch. Big House is only smash, a community that's already going to watch whatever Nintendo puts out regardless.
