So according to Amazon's website, there is a possible chance for shipping delays for Fire Emblem: Awakening. On the Amazon website for Fire Emblem: Awakening, it says that "Delivery of Fire Emblem: Awakening pre-orders may be affected by manufacturer shipping delays . Amazon apologizes for any inconvenience this may cause." Not sure if the delays will actually occur, however. Also, GameStop is apparently no longer accepting pre-orders for the game itself. They're still accepting pre-orders for the Fire Emblem: Awakening 3DS bundle, but not the game alone.
Just thought I would share this to let everyone know.

GameStop's Listing for Fire Emblem: Awakening
Notice how the option to add the game is not available on GameStop's page for the game?
The only reason that I can see for the shipping delay and stuff is that Nintendo of America wasn't expecting so many people to pre-order the game.
Also, apparently GameStop has reached their pre-order limit for the game, so that would be why it's not available for pre-order as the game alone anymore.
