VGCulture - New TWEWY

Official Site: http://www.square-enix.co.jp/subaseka/

There seems to be a teaser of some sort going on at Square-Enix that's related to "The World Ends with You" (TWEWY).  The page name extension "subaseka" is most likely the shortened form of the Japanese name "Subarashiki kono sekai" (It's a Wonderful World).  Speculations point out that this may not be a "sequel" but possibly a port, a spin-off, a manga/animé, or some sort of relation to another game (like the Kingdom Hearts game on 3DS).  It could very well be a 3DS port like Shin Megami Tensei: Devil Survivor had.  I can't say I'm excited since I haven't even completed the original game yet, but I'd like to see the series grow.
