In advance of Nintendo's E3 press conference next week, Nikkei has leaked out details on the Wii successor. The report (registration required) mirrors much of what has surfaced over the past few weeks.
Wii 2 will feature a new type of controller that includes a touch screen. The controller will give tablet-like controls to games, tapping the touch panel to control the characters on your television, for instance. The controller can also be used as a portable game machine.
