If memory serves me right...Nintendo only had one surprise at their E3 2012 conference, and it was labeled as Nintendo Land.
Nintendo Land is a collection of mini games inspired by Nintendo franchises. Each mini game has it's own rules and gameplay that falls into the world of that particular franchise. These mini games are not controlled by familiar characters such as Mario, Link, and Samus, but instead you will be controlling your Mii dressed up in an outfit that is fitting for that world.

I got to play on the team of four...and well...we did not do very well. I never felt like I got to fully appreciate the game since the guy with the tablet was so good. I guess it also didn't help that my teammates were not very talkative...but we will blame that on the loud atmosphere of the WiiU Experience.
The representatives at the event kept describing Nintendo Land as an example of what Nintendo is calling Asymmetrical multiplayer. I think Nintendo Land does a great job of this, but what worries me about the game is the possibility of an extreme lack of depth.
Nintendo Land seems to be the answer to the success of Wii Sports. Though Wii Sports was not incredibly deep, it had additive gameplay that kept players of all ages coming back for more. For Nintendo Land to reach the caliber of Wii Sports it is going to either need depth or addictive gameplay...lets see if Nintendo can deliever this.
