What copyright infringement? Nintendo used all those controller features way before Microsoft ever did. The traditional D-pad, analog sticks, the standard diamond shaped ABXY layout, handles, shoulder buttons, wireless and rumble. Most of which Nintendo actually was the very first to implement in a controller.
That said, it is heavily inspired by the 360 controller without a doubt, but it's no like if Microsoft could do anything about it, none of this stuff is patented really.
I'm personally can't say if I prefer the GC layout or this one for the sticks and I won't comment on it until I've actually played at least one shooter and one traditional platformer with one.
Also yes it has clickable thumbsticks.
no need to lecture me on nintendo controllers
i meant on the 360 controller
design, not so much the features, which is what i guess they can pull copyright on, since these people patent almost everything,
i really dont know, i'm just guessing, since i dont see a strong reason why nintendo would choose to deliberately place the thumbsticks there, other than that.
edit: grammar
