Both Western presentations take place simultaneously at 12pm EST. According to a tweet from Nintendo of America, the video will be about “more info on upcoming Wii U and Nintendo 3DS games!” So maybe an Animal Crossing: New Leaf release date, or some more Wii U eShop stuff?
The Japanese one, however, will focus on Wii U and stream here at 6AM EST.
In the meantime, here is a video in which Kit Ellis describes the differences between the DSi, 3DS, and 3DS XL.
PREORDER: Animal Crossing 3DS
