For those that can't read the bits, they're in plain text below.
- Make and share new Mii characters
- Easily interact with friends, family and people around the world with Miiverse
- Download add-on content, full games, classic games and applications from Nintendo eShop (all contents sold separately).
- Communicate with other Wii U owners in real time with Wii U Chat
Looks like we can expect VC content to continue on Wii U. Also, nice to see a confirmation of some sort of official chat channel on Wii U. Now we know how we'll be talking with each other!
