It's not relevant what the default control scheme is. People playing competetively will choose the best control scheme available. Your quote implied that Metroid Prime with WiiMote had the best FPS control scheme. I simply disagree. Even your quote said "It very nearly approaches keyboard and mouse.".
1) Read what DemoCoder's statement was that I was responding to, in particular the bit about traditional dual analog control.
2) Keyboard and mouse gaming on console is rare, and certainly not expected as a control scheme on a console.
It's quite obvious that the discussion revolves around normal game pad controls.
