RCR Wireless claims to have multiple sources telling it that Apple is planning on incorporating 3D technology into the next-generation iPad.
The fact that the iPad 3 is 3D is a dead cert, one Hollywood insider close to the big movie studios told RCR, adding that the screen would be the real magic. She went on to say that the big film studios were currently running around like blue arsed flies trying to gear up to release plenty of 3D content in time for Apples next launch.
Besides this "Hollywood insider", they also cite sources from iPad manufacturer Foxconn about the 3D plans.
We're not sure about the reliability of these sources, but Apple has clearly been exploring 3D technology over the years as evidenced by numerous patent applications. Not all of this research has been in the typical 3D technology found in recent movies and television sets. Some of the research has been in pseudo-3D technologies that involve head tracking that was effectively demoed in a recent iPad app. 3D, of course, has also been a big recent trend with the release of many 3D TVs, 3D movies, and Nintendo's 3DS handheld gaming console.
Also interesting is that this isn't the first time this has been suggested. Earlier this year, Japanese blog Macotakara cited their own sources who said that Apple's LCD supplier was beginning to manufacture small glasses-free 3D LCD panels for the iPod touch, though they suggested it might involve user head-tracking to accomplish the effect.
