That catchy music...that art style....is this what I think it is??!?!

Yup, that's definitely a remix of "Calling." *fanboy squee*

Yes, after five years, Square Enix is finally going to make a big The World Ends With You-related announcement! It's not necessarily a game, but a 7-day countdown teaser site probably wouldn't be for anything small, and they should definitely know how jumpy the fans are.

Side-note: Apparently the site will add new layers of music with each passing day. It also turns out that you can mess with your computer's clock to make the countdown advance, but only a few days. (It brings back memories of messing with the DS clock to cheat Shutdown PP...ah, good times.)
