Nintendo's press conference was arguably the most entertaining and engaging of the big three. In typical Nintendo fashion, the company introduced a new theme, "Playing = Believing." The media briefing itself began with the legendary Shigeru Miyamoto appearing on stage (to huge applause, naturally) with Wii controller in hand. He proceeded to conduct a virtual orchestra as it played the theme to Legend of Zelda.

Conducting music is but one of many gameplay possibilities the Wii will offer. Nintendo demonstrated a number of titles including a Wii Sports compilation which features baseball, tennis and golf, Metroid Prime 3 Corruption, Super Mario Galaxy, Excite Truck, WarioWare: Smooth Moves, Red Steel, among others.

What really stole the show, however, was a live demo of The Legend of Zelda: Twilight Princess, which Nintendo revealed would be made available in two versions on Wii's launch day. The GameCube version will play as a typical Zelda GameCube title, while the Wii version will make use of the Wii controller for added functionality such as sword slashes, pointing and shooting arrows or a grappling hook, fishing, and more. Reggie Fils-Aime, Nintendo of America's executive vice president of sales & marketing, proclaimed that Twilight Princess is the best Zelda game ever made.

Nintendo also revealed its final two secrets, although exact price and date information is being saved for another time. Secret #1 is that the Wii controller will include a speaker emitting occasional sounds to add to the immersion factor through positional audio. For example, if Link shoots an arrow you can hear the pulling back of the bow and subsequent release as it snaps, and then the sound will move to your TV/sound system speakers when the arrow makes contact. Secret #2, as some in the industry had guessed, was revealed to be motion sensing technology in the nunchuk attachment as well. With a sensor in both the main Wii Remote and the nunchuk controller all sorts of possibilities are opened up to developers. Just a few examples include the use of a sword in one hand and a shield in the other, or a clamp and a scalpel, or a pair of boxing gloves.

"The Wii console gives every game developer a tool to create new experiences, not just linear advancement," said Fils-Aime. "It will attract all kinds of new players, and thoroughly satisfy the hard-core gamers."

"Not only is Wii compelling to current game players, but it also will entice new players with new experiences," added Nintendo President Satoru Iwata. "To expand the total number of game players, we must make our experience both friendlier and more compelling. With Wii, it is."

Nintendo also briefly touched upon what they're calling WiiConnect24, which represents the Wii console's low power consumption (as low as a miniature light bulb) and "sleepless" feature. Users never need to turn it off and therefore content downloads can take place even when you're not using the console. The Wii will also be able to start up very quickly and enable players to get into their games without delay.

Reggie also revealed that 27 different Wii titles would be shown off on the E3 show floor, and while not indicative of the system's launch lineup it's a good sign that such a wide variety of software is already in the works. GameDaily editors will be bringing you hands-on impressions of these Wii games.

While Wii was no doubt the highlight of the briefing, Nintendo also took the opportunity to trump the success of their Nintendo DS handheld. The system has sold a whopping 16 million units to date, and by the end of this year over 100 new titles will join an already formidable library. George Harrison, Nintendo of America's senior vice president of marketing and corporate communications, introduced the term "Touch Generations," which represents Nintendo's more unique DS offerings, such as Brain Age. "We remain committed to going where others can't - or won't," said Harrison. "By grouping our innovative DS games together under the umbrella term 'Touch Generations,' new players will easily be able to identify games designed for them."

In addition to the already announced New Super Mario Bros. and The Legend of Zelda: Phantom Hourglass, Nintendo introduced more promising DS titles including a new Star Fox, Pokemon, DK King of Swing, Diddy Kong Racing, Elite Beat Agents, Yoshi's Island 2 and more. As was previously announced, the DS Lite hits the U.S. on June 11 for the price of $129.99.
