Nintendo of America has just released their first party US release schedule for everything but the Wii U (DS, 3DS, and Wii). Although the games themselves are probably going to be released to critical acclaim and high sales (Kirby's Dream Collection is already doing very well in Japan), many of them don't have any actual release dates, or even targets.
The Wii has a whopping one first party US release, seemingly before it dies: Kirby's Dream Collection. The DS has two, but they're essentially the same game, in Pokemon Black and White 2.
The 3DS is by far their strongest US presence, but again, there is only one actual hard release date: August 19th for New Super Mario Brothers 2. Animal Crossing, Fire Emblem, and Smash Bros. are all reconfirmed for the 3DS, none of them have even have release windows at the current time.
Of course, in light of this paltry schedule, make sure you don't discount the Wii U, which hasn't officially revealed any release dates at all. Provided you're willing to drop a yet-to-be-revealed sum of money on it, you should be good to go in terms of Nintendo love this Holiday season.
