Posted below is a new "Ponyo On A Cliff by the Sea" trailer, from the French-language release.
This is all hand-drawn, from director Hayao Miyazaki and Studio Ghibli. Those who have seen it describe it as “very similar to 'My Neighbor Totoro' in tone, with a simpler plot that focuses more on the emotions of the young protagonists than anything else, and the animation is gorgeous.”
As usual, Daniel Thomas MacInnes' "The Ghibli Blog: Conversations on Ghibli" provides the best coverage leading up to the U.S. release of the film (by Disney) on August 14, 2009 :
