Sony has filed a patent for a 3D controller which works well with its latest console as well as Vaio PCs. This controller responds to hand movements as well as the way your hand grips around it and applied pressure. The inclusion of a tactile response makes gaming more immersive, something which Sony looks set to backtrack upon when it mentioned rumble is so last gen. I guess this must be the next-next generation game controller it is talking about to go with its latest console. /sarcasm. There is no word on when this patent will ever see the light of day though, so in the meantime just be content with half-hearted motion controls on the Sixaxis.
