If there is a game or another application already running , the Wii U GamePad 's HOME button ring will flash indicating that there is an incoming call . The idea of the feature was originally seen in the introduction trailer of the Wii U in E3 2011 . However , users were n't also able to use the service as a multitasking application , therefore not having the ability to make video calls without interrupting game play . Nintendo had announced a desire to make video chat possible through multitasking , but it was never implemented
