No joke title. There was a trailer for this game on the showfloor at E32010, but it was kept private and only shown to select people. IGN was able to see it, but of course, they can't show the video, but they did describe it as best they could:

lol I can't wait till the trailer is finally shown. I doubt it will though until E32011, sadly.
Remember, this is NOT a remake of anything. Tetsuya Nomura said that this is a new game entirely. No news as of yet why Sora and Riku are in their original outfit, and why they appear to also have their younger look, too. We'll have to be patient for more info. Sora and Riku are the playable characters. Yipee!
