Disney released the official Alice in Wonderland website (it's not as fabulous as it should be.) Go check it out, but there isn't a whole lot to explore, hopefully they'll be adding to it soon.
If you're alright with spoilers, www.cc2k.us has an Alice script review, but don't read it if you want to hold out and see the movie with fresh eyes. (Frankly I don't think the author of the article was to terribly happy about writing the article, and he's not the biggest Burton fan, but it's still intriguing.)
Here's a first look at the logo for Alice in Wonderland from Collider, I'm sure it'll end up being added to and become little more spectacular, but the simple creepiness seems pretty fitting for the Burton film.
