According to a post on NeoGAF which features a picture of what appears to be a shot taken from GameStop’s database which shows that Xenoblade Chronicles will be released in the US on April 3,2012. The key thing here is that it may be a GameStop exclusive release. Of course, this is just speculation at the time, with Nintendo saying nothing on the matter. Either way I would be pretty excited that this game is getting localized even if it will only be sold at GameStop.
On a side note I also like how GameInformer which is a child company of GameStop put this down as a rumor.
