Also, a new Speed Boot mode is coming early summer.
Games using the Wii U GamePad's Near-Field Communication (NFC) functionality will be demoed at E3 2014.
Also, an early summer system update will make use of a new Speed Boot Menu option that will allow GamePad users to start up the game quickly. See how it works in the short video at the bottom of this news story.
The usage of NFC and the Speed Boot Menu is part of an effort made by Nintendo to refocus their efforts on what makes the GamePad unique. While Pokémon Rumble U has used the NFC capabilities, it has largely been ignored by both first and third party developers.
Games such as Skylanders and Disney Infinity have shown ways to bring NFC technology to games, and Nintendo may very well use these titles as inspiration. The technology is inside of every Wii U GamePad, even if most gamers aren't aware. It can also be used as a payment system with compatible credit cards.
