Do you think apple will do anything with 3D on the ipad now that they have the resolution?
It's already been done. There are some games that draw the screen based on the position of your eyes (seen with the front-facing camera). The only drawback to this is that the 3D doesn't pop out of the screen, but looks more like you're looking deep into the screen and seeing stuff below it.

its a non working trick. i dont see depth at all. i do believe it can help for a true 3d screen to make it a bit better.
Download the app and try it yourself. It's hard to see what's interesting about it from the video, because the iPad isn't tracking YOUR eyes.
