Square Enix has launched a new teaser site. There have been a number of things that point to this being related to The World Ends With You.
One interesting bit is that the countdown uses the same font as the DS game. The second is that the music that is being played is “Calling” from TWEWY with extra layers of instruments added each day (with lyrics on the final day). One other notable bit is that the footer says “CHARACTER DESIGN:TETSUYA NOMURA & GEN KOBAYASH” which people may know worked on TWEWY. Could this mean a sequel to the critically-acclaimed DS RPG on the 3DS? We’ll find out soon!
