You know, I've never understood this "surprise/don't read anything" idea that the Zelda community seems to embrace. I read every article on Twilight Princess, Phantom Hourglass, Spirit Tracks, and you know what? Those games weren't ruined for me at all. I still enjoyed every bit of them (except for a few obvious parts that most hate), and those spoilers didn't change how I felt playing through the game either.
I've read just about every post about Skyward Sword to date, I've seen all the pictures, and I've watched all the videos. I know for sure that when I finally play it, what I see now won't really make a difference to me, as I'll find the game just as new as I would without spoilers.
And to be truthful, if this game is as large as it's supposed to be, we've seen nothing of what this game has to offer.
