The developers of the November’s Sly Cooper are contemplating adding a slider type control to be able to control the depth of the on-screen 3D. Which they are hoping will give players more positional flexibility when playing their game. If this experiment works we could possible be seeing added to other PS3 3D games.

Yes a slider makes sense because it allows players adjust the 3D to where they are sitting. My question its, being a Nintendo fan-boy, did they have this idea before the 3ds?
