There are a few dots to connect, however: 3D gaming is on the rise, and a few other companies have also experimented with head tracking as a way to implement 3D effects. Nintendo's own Satoru Iwata hasn't been impressed with 3D gaming in the past, but his issue is with the glasses, not the technology. "I have doubts whether people will be wearing glasses to play games at home," he said recently. We've also heard that the next handheld would have a "movement sensor" of some kind, so if Nintendo really has designed a head-tracking 3D solution, then maybe the console is ready to go. The press release, which you can read after the break in full, says we'll see more at E3, so stay tuned.
