A year ago, Nintendo at E3 2010 announced the Nintendo 3DS. The release date and price (for Japan) was later given at the Nintendo Press Conference 2010 (September).

Hoping there will be another Nintendo Press Conference for this year, we'll learn more about the Nintendo Wii U and others, like the exact release dates for Super Mario (Working Title), Mario Kart, Kid Icarus: Uprising, Luigi's Mansion 2, and Paper Mario (Working Title). Hope we'll also see the final version of Paper Mario (Working Title), and finally know the official sub-name of the game (haha, imagine "Paper Mario: The Attack of King Paper-Cut")

We'll probably hear more news from Nintendo regarding Wii U and all those upcoming games for the Nintendo 3DS REALLY soon.
