Nintendo's Satoru Shibata revealed the news during this morning's (June 22) Nintendo Direct presentation, confirming that both Animal Crossing and Fire Emblem would launch next year.
"In order to provide the best end result and give fans the quality they expect from Nintendo, we can confirm today these two titles will now be launching in Europe in the first half of 2013," explained Shibata.
"We are sorry you will have to wait a little longer but we hope you understand our desire to ultimately deliver a game fans will love."
Animal Crossing 3DS adds swimming, extra village and household customisation options and the chance to dress up in Legend of Zelda costumes.
It also contains StreetPass functionality, enabling players to view houses and towns from other users.

Fire Emblem, meanwhile, was first announced during Nintendo's pre-Tokyo Game Show presentation, and will feature co-operative play for the first time in the series.
It was also thought to be the first 3DS game to offer paid DLC, until it was revealed that New Super Mario Bros 2 would add paid post-release Coin Rush levels.
Nintendo also announced the 3DS XL at this morning's presentation. The updated device features bigger screens and a better battery life.
