When I look at the graphic (
http://developer.apple.com/wwdc/) for the 2011 WWDC, it makes me think that the 3D rumor may be accurate. Note the many 3D patents that Apple has been awarded over the past couple of years for precisely this type of thing. And the fact that Apple has used their graphics on prior occasions to tease what would be revealed at the event - most recently, for the iPad2 and how they teased the SmartCover...
I dont know if 3D is dependent on hardware (most of Apples products have front facing cameras at this point at least), or if it can be driven by software alone on existing devices.
Thoughts?
