Nobody expected to see the Nintendo Switch that night
The whole presentation was very deceitful. Jimmy was told by Reggie Fils-Aime, the president of Nintendo of America, that he would be testing a level for the new Super Mario Run, the first Mario game to ever appear on iOS by Nintendo. At this point, Jimmy Fallon was a little nervous. He was then told that Shigeru Miyamoto, the creator of Mario himself, was right there, in the crowd, watching him. Of course, this added a little more pressure. The creator of Super Mario was about to watch him play.
Right after the very exciting test, Reggie told Jimmy that he had another surprise for him. From under a question block, Reggie unveiled a Nintendo Switch, which marked the very first appearance of the device in public. Needless to say, Fallon was incredibly excited.
When the console was unveiled, Jimmy was passing around like a child on Christmas. He was, as he himself puts it, "geeking out". At first, it seemed that that was it, but Reggie clarified that they were going to play one game.

Reggie Fils-Aimé then proceeded to blast The Legend of Zelda: Breath of the Wild right in front of the audience. Many have speculated about the performance of the game in the Nintendo Switch, in comparison with the Wii U. Most of what could be said is hampered by the fact that YouTube does not play the Tonight Show's videos at 60fps and because of this, it is impossible to recognize whether the game runs faster or not. The draw distance and definition do look sharper, though.
While Reggie was showing some aspects of the game, Jimmy Fallon was constantly asking for the controller as he really wanted to play the game. You can see that, due to this, Reggie was forced to introduce the Switch characteristic of the console by switching from screen to tablet in order to hand the gamepad to Jimmy Fallon. Through this exchange, Reggie stated that the tablet is the whole console, nothing is left in the Switch's stand. The graphics do seem to get a slight downgrade when the game is running on the tablet's screen, but it still looks awesome.
Without a doubt, Nintendo took full advantage of the situation and showcased two of their most expected products. From a marketing standpoint, this showcase was genius. The video is just three days old and already has more than 4 million views. Reggie stated that some new information will be released in January 12th, 2017, so all we can do for now is wait.
