1 - The official Pixar site has been "Brave-a-fied". There's not a ton to see here but it's just a nice visual to see Brave emblazoned across the homepage.
2 - The Official Pixar/Disney Brave page - A great place to get wallpapers (for your computer, iPad, iPhone, etc), learn about the characters, view photo galleries, read a brief background on the story of Brave and watch trailers.
3 - Also, if you haven't pre-ordered your The Art of Brave book, head to Amazon to do so - just click the link above.
