A U.S. release for the DS sequel is still not confirmed.
Okamiden is now trademarked in North America, according to SiliconEra.
The name was also trademarked in Europe recently, and while this still
doesn't confirm a release outside of Japan, it makes it very likely.
Capcom also trademarked Ghost Trick, a puzzle game already confirmed
for a worldwide release, and Exed Exes, which is a vertical
shoot-'em-up that originally came out in North America as Savage Bees.
Okamiden is set for a 2010 release in Japan.
