The Wii U Console:
- IBM Power® multi-core processor. No word on number of cores or clock speed.
- GPU – Unspecified, but probably an AMD GPU like the GameCube and Wii.
- Backwards compatible with the Wii. GameCube compatibility unspecified.
- No Hard Disk Drive.
- Built-in flash memory. Size unspecified. Can be extended via SD card or by USB drives.
- USB connectivity is four USB 2.0 ports.
- Video formats supported: 1080p, 1080i, 720p, 480p and 480i.
- Video output: HDMI and Nintendo’s AV Multi-out.
- Audio: 6 channel linear PCM via HDMI. (6 channel is likely 5.1 surround.)
- Optical Drive: New ‘high density’ format (so not Blu-ray) 12cm optical disks. Will play Wii optical disks. Slot loading as with the current Wii.
- Connect up to four Wii remote controls (or Wii remote control pluses). Your nunchucks, classic controllers, classics controller pros and balance boards will all still work.
The Wii U Controller:
- Screen: 6.2 inch, 16:9 widescreen. Resolution unspecified.
- Screen is touch-sensitive. Almost certainly resistive, not capacitive.
- Stylus is stored in the top edge of the controller like the 3DS.
- Buttons: power, Home, d-pad, start, select, A, B, X, Y.
- Shoulder buttons: L and R, plus twin triggers ZL and ZR.
- Accelerometer and gyro for sensing your waggle.
- Front-facing camera.
- Headphone socket on the top edge.
- Looks like a covered AC Adaptor port on the top edge too. No word on the controller’s battery capabilities.
- You can also see an expansion port on the bottom edge of the unit in the pictures, similar to that on the Wiimote, though it looks like a different shape. No word about that from Nintendo.
