I'm afraid of Skyward Sword being spoiled for me like Super Smash Bros. Brawl (darn you Smash Dojo!) was in 2008. Do any of you share the same feelings?
We barely have enough info to be spoiled. If anything, we've seen about 5% of the entire game.
No, Nintendo seems to have given us the basics. We're not even sure if Ghirahim is the main villain (and if it was confirmed then I haven't heard of it yet.
As for Brawl, I wasn't spoiled by its site. It's not an all-out adventure title (disregard Subspace Emissary) like Skyward Sword will be. I actually liked seeing who'd be in it (but on the main a friend let me know it by phone...about each time he noticed it was updated). So, I'm content with what Nintendo has displayed so far.
