Well, as for me personally, I'm going to find out what the roster is(not how to unlock them) and then leave the Internet alone until I figure out as much as I can by myself.
After that, of course, I'm going to be right back here with everyone else talking about new info, strategies, etc.
So yeah, expect about a month of nothing but "how do you unlock X" and angry Europeans/Australians seething about the fact that we're playing Brawl while they're reading forums. I weep for you, my European/Aussie friends.
And honestly, I don't think -anybody- is going to miss the character support threads or the roster predictions. They were cool for a while, but after a year and a half, I think everybody is ready to know who's in and who's out.
