Yes, I have a background on my computer for WALL-E! And I've seen all the traliers. I can't wait! However, after WALL-E, it looks like Pixar are going for a plummet. Ask me for more details.
One of the cool thing about the movie is there is almost no dialogue until about half way into the film. Even then people do not speak in long sentences and you can get the meaning quite well without completely understanding the words. Since I'm hard of hearing I found this to be a real plus. It also made me think that Wall-e would be a good film in any country, regardless of the language there.
