launched an official website for The World Ends With You, which had nothing on it besides a pointless countdown. While the website actually has stuff to look at now, it's still relatively "meh" as far as official sites go.
The Square Enix Members page is a different story, though. There, you can check out a creator's roundtable, as well the first chapter of the translated manga by Shiro Amano (with more chapters to come). Another neat feature is that by clicking on the few colored bits of the manga, you can unlock TWEWY ringtones. They can be downloaded for free once you're finished reading the chapter (this blogger's favorite of the ones offered is "It's So Wonderful.")
The website also reports that the official soundtrack for the game will be heading to iTunes soon, which is good news if you don't mind having DRM "protected" music.
