Looks like Sony has been paying attention to what Nintendo is doing. They have announced that future stereoscopic 3D titles on the PS3 will come with a 3D slider that allows you to adjust the depth of 3D displayed by the game. It’s similar to how the 3DS handles 3D.
The adjustment can be made using the left analog stick, using a tilt. Do you have your 3D TV yet? I doubt the phenomenon will last long, but it will be interesting to see what happens.
