Still don't want a Wii U? This is what Nintendo would say to convince you

LOS ANGELES — The Electronic Entertainment Expo tradeshow can sometimes feel like it’s all about Sony and Microsoft. But Nintendo isn’t letting this week slip by without having a say of its own.

Coming into E3, the Japanese publisher still really had only one main mission: Sell the world on the Wii U. It hasn’t had a lot of luck with that so far. The company has only sold around 6.5 million Wii U systems as of April. That’s less than the 7 million PlayStation 4s Sony has sold despite releasing that console a year after the Wii U. But Nintendo thinks it’s building a strong case to convince skeptical players, and it spent E3 detailing its argument.
