Just finished watching Nintendo pre-E3 direct conference where they showed off some of the Wii U’s features. There’s in integrated forum in every game. For example, they showed a guy who was having trouble in killing a zombie in a shooter game, so he actually paused the game and opened a menu on the controller where he could see people’s answers who are also stuck on that exact same spot. This forum can be typed on normally, or handwritten using Wii U’s gamepad.
They showed off the Wii U Classic Pro Controller, which is essentially a Xbox 360 controller for those developers too lazy or uninovative to make use of the main screen. This allows for local multiplayer gameplay between friends.
They showed that even the singleplayer games have online connectivity. For example, they showed off a New Super Mario Bros. gameplay towards the end of a level near a flagpole, and when Mario died close to the end and the screen faded to black, up pops little messages from people who died near the same spot and it showed what they had to say about it.
The Wii U controller functions as a webcam, and you can livechat with anyone on the Nintendo Network.
That’s about all they showed I believe. I’m looking forward to see what else they throw out this Tuesday.
EDIT: Forgot some small details. The tablet controller has clickable sticks now, as well as new grips on the back. The controller is also a universal remote for your TV. Watch the pre-E3 demonstration right here: https://www.youtube.com/watch?v=9AkPdAWfFjI&feature=g-u-u
