Luigi's Mansion: Dark Moon and Animal Crossing are still set for the first half of 2013.
Brain Age: Concentration Training, which came out in Japan in July, is getting delayed to Q1 2013 in North America. The game was originally slated for a December 3 release.
The reveal of the delay was buried in Nintendo's mid-year financial report, which also shows Luigi's Mansion: Dark Moon and Animal Crossing 3DS slated for release during the first half of 2013.
In Europe, Luigi's Mansion: Dark Moon is set for a Q1 2013 release, Fire Emblem 3DS is set for a Q2 release, and Animal Crossing and Brain Age: Concentration Training are just listed as 2013 releases. In Japan, Luigi's Mansion: Dark Moon is just a 2013 release.
The only other two future 3DS releases in the report are LEGO City Undercover and Super Smash Bros., both of which are set for a TBD release in North America and Europe.
