The latest Nintendo release schedule doesn't narrow the release windows for many highly anticipated 3DS games.
Mario Tennis and Luigi's Mansion 2 are both labelled up as 2012 releases. Animal Crossing and Paper Mario are down for 2012 in Japan but are both listed as "to be determined" for North America and Europe which, in a worst case scenario, could lead to — gulp — 2013 releases.
Sadly there's no mention of Fire Emblem Kakusei or Monster Hunter 3 G for either Europe or North America. In fact, the only mildly notable confirmation is that Spirit Camera: The Cursed Memoir is definitely coming to Europe, so that's something at least.
