Earlier this week, Square Enix created a teaser site for an upcoming The World Ends With You announcement. There's still over two days until the big reveal, but it looks like the information got out a bit earlier than the publisher was planning.
Andriasang noticed that the company updated its e-Shop with a listing for a new TWEWY soundtrack, which then goes on to confirm the game's upcoming release for the iOS platform. Square Enix has since taken the listing down, but alas, the news has already been spoiled. Nice work, guys!
This is almost certainly what the teaser site is set to reveal, though there's always that sliver of hope there is more for fans of the franchise. A sequel perhaps? Please? Pretty please?!
