Nintendo's first TV ad for the Wii U, which aired during the latest episode of Homeland in the UK (via Polygon), lays out exactly what the November 18, 2012-releasing console can do. There's a feeling of goofiness that seems out of place for a Sunday night audience, but the content of the ad is exactly the sort of thing that Nintendo needs to be putting out there.
Starting with the declaration that this is "a brand new console with a brand new controller," the ad runs through a variety of Wii U-specific features that set the new console apart from the Wii. You get looks at a handful of games, but none of the titles are actually mentioned. Nintendo smartly puts the focus here on the hardware and letting people know how they'll be using it.
