- Nintendo wants to use the Wii U name but some trademark troll is giving them grief over it for whatever reason and they've got a backup plan in case they can't use it.
- Rumours of it being weaker than PS3/Xbox 360 untrue, Nintendo annoyed about them.
- Haptic bio feedback considered, not decided
- NDAs stop publishers from talking about the console and upcoming games much, making it difficult for Nintendo to get the news out
- Release date possibly November 18th 2012, no decision made
