I suspect it's a JRPG by Monolith Soft which will probably never make it outside of Japan. I'm now gonna dream of E3 2011 where Nintendo announces The Last Story, Xenoblade and this for the West...if that happens I can die happily.
PS: On the teaser site, instead of sx3j type in sx4j and it takes you to the Xenoblade website. The game logo also reminds me of them too and they have finished Xenoblade not too long ago and are working on a new game since. That's why I suspect that it's from Monolith Soft.
