User blog:King Marth 64/Awakening releasing on March 31st, 2013?

I found this link that someone gave it to SF.net in the Nintendo Direct NOA Trailer thread a while ago and it said on GameStop website that it saids that Fire Emblem: Awakening will be releasing at March 31st, 2013. I am not sure if this might be a true release date or another mistake for 2013?
