Hideki Konno, one of the key personnel behind the development of the 3DS, stated that the 3DS's ability to produce 3D without glasses was paramount to its now practically guaranteed success.
"I think at Nintendo, we realize that any sort of goggle-type 3-D technology was not going to work," claimed Konno. "In order to make 3D technology viable with video games, we thought we needed to have glasses-free 3D."
Reggie Fils-Aime echoed those comments, claiming that glasses-free 3D was paramount, to the extent that they probably won't pursue any kind of 3D with their next home console.
"Glasses-free is a big deal," Fils-Aime said. "We've not said publicly what the next thing for us will be in the home console space, but based on what we've learned on 3-D, likely, that won't be it."
