Square Enix is teasing a new title featuring character designs from Tetsuya Nomura and Gen Kobayashi.
Here's the official website. Aside from the "Subaseka" name that might indicate the Japanese title of TWEWY, that teaser page also has a similar style. Is this finally a sequel to the critically acclaimed DS RPG? I hope it is, and we'll know in six days, apparently.
Also, the music on the website apparently sounds like TWEWY music (though I can't get it to work on any browser I try it on).
