Concrete answers have been ambiguous, but according to a few different retailers, Fire Emblem: Awakening has been delayed by a few days.
I called a few Best Buy and GameStop stores, some nearby, some far away, and most were reporting a small delay. The Best Buys I spoke to said the game probably wouldn't be available until Wednesday February 6, and the GameStops said the game may not be available until Friday, February 8 due to shipping errors. Amazon also has a notice on its Fire Emblem: Awakening page that reads, "Potential Shipping Delay: Delivery of Fire Emblem: Awakening pre-orders may be affected by manufacturer shipping delays. Amazon apologizes for any inconvenience this may cause."
I sent an e-mail to Nintendo representatives for further confirmation, and will update the story if I hear back.
If you have the game reserved, or were planning on picking it up tomorrow, I would suggest calling ahead and confirming a release date if possible.
To live vicariously through us since you might have to wait a little bit longer for Fire Emblem: Awakening, you can watch us play the game in a recent Test Chamber, or read our review here.
