Wii U will support two GamePads, but not with out a huge effort from the console manufacturer

One of Nintendo's top Wii U execs has talked frankly about the challenges support for two GamePads has brought the team behind the forthcoming console.
At yesterday's Nintendo E3 press conference, it was revealed that the Wii U will support two of its distinctive GamePads. The reason that fact impresses is because, along with gyros, a camera, a microphone and various other inputs, the GamePad features a relatively large touch screen.

Developers will likely be delighted that they can design games around three screens – the main television and the GamePads' 'single player' screens.
However, for Nintendo's engineers to create a device that could fill three screens with visuals using only one processor and a single graphics chip took a significant effort, as revealed by Wii U hardware producer Katsuya Eguchi at a roundtable press conference at E3.
“The reality is it takes processing power to draw an image on a single screen,” said Eguchi during the roundtable, speaking through a translator. “If you add a second screen, it requires extra resources from the hardware. There are hurdles we have to overcome. But by implementing another screen, it adds more innovation in game play and it makes it more fun.”
