A QA tester at Traveller's Tales Games has leaked an image depicting a redesigned Wii U controller.
Posting the picture on his Twitter account, which has since been deleted, the revised controller of Nintendo's forthcoming console features several minor changes, in addition to the implementation of analog sticks, which replaces the nubs.
Other notable changes, albeit minor ones, includes the Start and Select buttons being moved to the controller's right side. Also, there's Wii U branding placed on the controller, as well as a mysterious square on the left side of the tablet. A comparison of the old Wii U controller and the revised one can be viewed below.
Nintendo will reintroduce the Wii U during its E3 press conference next month, so it shouldn't be too much of a surprise if the above controller revamp is what's shown.
