Despite announcing support for two Wii U Gamepads per console during their E3 Media Briefing, Nintendo reckons that compatible games won't arrive until "well after launch," as developers will need time to integrate them properly.
Speaking to Gamasutra, NoA boss Reggie Fils-Aime believes that developers will have to get used to the concept of Asymmetric Gameplay before working out how to implement dual Gamepad support in a meaningful way.
Games need to be built that can take advantage of the two GamePad controllers. It's going to be well after launch for those game experiences to come to life.
Asymmetric gameplay is going to be the next major step forward, just like active play was when we launched the Wii. We think that's where developers will focus first, then there will be multiple experiences that have two GamePads.
Reggie went on to suggest that the Gamepad's NFC (near-field communications) functionality will potentially be a major unique draw - even stating that Pokemon fans have been badgering them to support the new tech. A Pokemon game in the vein of Skylanders doesn't sound too bad to us, so long as it doesn't come at the expense of core gameplay.
