Grasping at straws in a **** storm, I'm afraid.
Instead of hoping there's more than what you've seen, just go into denial like I have. Whenever I see a "spoiler" that isn't backed up with a picture or a video, I automatically convince myself it's not true (even though it probably is), so that when it ends up being in the game, I at least tricked myself into being surprised.
With all the pictures and youtube links that I'm sure are floating around the Brawl boards right now, I'm sure very few of those types of spoilers exist, but hey, it's something.
