Here are some more Toy Story 3 character banners with more to come, presumably. They come from Moviefone, ComingSoon, Yahoo, and /Film respectively.
As a bonus, the new trailer an be found over at /Film as of right now, and will officially be online Monday 9AM PST. It looks fantastic especially seeing Andy now as opposed to ten years ago with everything Pixar has learned since then.

watched the trailer for this earlier, and it doesn't look too bad. The animation is AWESOME and has came a LONG way from toy story 1 & 2.
