Nintendo produced a few slick videos of its various console lineups for its conference. You'll have to click over to the 3DS, Wii and DS pages of Nintendo's conference site to see them, but it's worth the extremely small effort.
In addition to footage of known 3DS games, including Super Street Fighter IV 3D Edition and Professor Layton and the Mask of Miracle, the 3DS video reveals a second Resident Evil game, Biohazard: The Mercenaries 3D. The Wii video offers the first look at the new Fatal Frame and Rhythm Heaven games, among many other first- and third-party titles. And though you have to wait until the end, you will see clips of the new Kirby game and Battle & Get! Pokemon Typing DS in the DS video.
