Piracy can't be hurting publishers that much; otherwise there would be more demand for a less easily pirated storage medium. Look what happened with the Gamecube - it had a difficult to pirate medium and none of the publishers really supported it.
I know it was still possible to make back-ups, but it was more difficult. Who doesn't own a dual layer DVD burner (all that is required to burn Wii and XBOX 360 games)?
