Having an idea and using it are two different things. Not to meantion, analog and rumble were PC features first too. Yet, bringing them to consoles is, apparently, widely considered a horse of another color. As Nintendo gets the credit for them.
Tho the Wii doesn't use gyros, so no one is arguing they stole it directly, Sony just "magically" decided to add it after Nintendo announced it.
Anyone who thinks that it wasn't added as a direct response to Nintendo is retarded. Not saying it wasn't smart of Sony business wise tho.
