Nintendo copied the concept of lightguns. Nah they didn't copy anyone, but they didn't invent the concept of motion technology so can't reserve the right to say that anyone copied them.
Microsoft copied Sony.
Sony copied no one.
Just how I've seen it. Probably you can trace the eyetoy back to something before it and say Sony copied someone there if you'd like. I don't think it really matters anyway.
