It appears that Nintendo of Europe might have jumped the gun too soon, because they might have announced the Nintendo 3DS release date sooner than expected. If this rumor is true Europe should have the 3DS in their hands on March 2011, and they will have Paper Mario 3D on March 25th, 2011.
If this release date is true, and Nintendo is sticking to releasing their products last for Europe; then I am predicting that America might get the 3DS in January or December. We will keep you updated as this story continues to develop.
Update: Reggie Fils-Aime said that they are planning on shipping the 3DS to all of their major markets on March 31st, 2011. No details were mentioned about specific release dates, but we will keep you posted.
