Sony patents PowerGlove, but didn't The Wizard patent that?

The following is a quote stemming from Sony's latest patent submission: "The central body and at least one protrusion are configured to capture a user's hand movements." Hand movements... protrusions... that picture! It's pretty much the PowerGlove from that 80's movie, The Wizard. That damn glove helped him to kick ass at Mario Bros. 3, so perhaps the same design will assist in conquering some PS3 games.

Also included in this patent are a number of claims. These range from measuring the movement and bends of your individual fingers all the way to the inclusion of force-feedback. If this thing actually came to exist, it would be pretty sweet. Not that it would be practical or anything, but it would be cool to try out. We could all turn out to be Wizards, you know.
