Nintendo Reveals New Wii Classic Controller

A brand new version of the classic controller has appeared on the Japanese Nintendo website. The "Classic Controller Pro" features a few differences from the original, including hand grips, adding more space between the analog sticks and includes two rows of R and two L buttons up top.

The controller presumably plugs into the Wii Remote, just like the original classic controller.

The controller will hit store shelves this summer, hopefully in the U.S. as well.
