Community - Retro - Hardware - Prototype Wii U Gamepad I recently procured.

It's actually very different from the released version Aside from circle pads vs analog sticks. Start and select on the bottom, no TV button, different looking buttons, different port etc

What game console/handheld prototype looks better than the final product?

Wii controller prototypes included star-shaped design, was met with opposition

I've compared the prototype E3 gamepad against the retail version. Nintendo did make some changes after the E3 in 2011 when they exhibited the console. : r/wiiu
