The pre-E3 Nintendo Direct just ended. Even though it was hardware-focused, some pretty nifty stuff was revealed:
-Official controller name is "Wii U Game Pad". Besides all the crap we already knew (gyroscope, touch screen, sensor bar, camera, NFC, etc; there was an interesting bit using the gyroscope with the screen to catch a fly ball from first person view in Wii Sports Baseball), Nintendo finally discovered "clickable" analogue sticks, and it also works as a universal IR TV remote. As speculated, the blank square below the D-Pad is the NFC communication point.
-WiiU web browser was shown. You can open and close a curtain over the TV screen while browsing on the Game Pad, nifty for sharing internet videos in the living room.
-Some manner of art app was demoed on the Game Pad, showing a color drawing of Link (TP style with simpler shading; looked kinda water-colory).
-Last year's Zelda demo surfaced again. This close to launch when they told us it wouldn't be an actual game? Hmm...
-Game Pad Pro, a more compact controller without the screen, will also be offered.
-Nintendo's basically making every game on the face of the earth, whether single or multi player, into a social affair with MiiVerse. In the WiiU's main menu, Miis from yourself, your friends, and people you don't know who just happen to play the same games as you, will cluster around the game icons. Popular games you don't own may also appear. At any point you can suspend gameplay and access chat rooms specific to the game you're playing, with your Miis acting as avatars. You can both type and draw. Video chatting was also shown while gameplay was suspended. Also it is possible for comments from people at the same point in the game as you to pop up during gameplay (regardless of when they were playing that point in the game). In the future, it will be possible to check MiiVerse chats from smart phones and the like. Game Pad screen was described as a "window" to MiiVerse chats, possibly suggesting the ability to view them during gameplay as well.
-Some NSMBWiiU footage was shown, with Mario only. Pop-up MiiVerse comments were demonstrated when Mario died, and during the level select map. Backgrounds had a slanted crystal look reminiscent of Super Mario World, overall with much prettier and more diverse colors than the 2011 demo.
