3DS initially lacked 3D and motion sensing, probably wasn't called 3DS

According to Hideki Konno, group manager of the 3DS hardware project, early 3DS prototypes didn't feature the glasses-free 3D screen that has become the system's main selling point, and the feature wasn't even considered until early 2009, when Nintendo demoed the "really impressive" technology.

"I became involved with development starting in 2008, but at that time, it didn't have 3D visuals," said Konno in a recent Famitsu interview, according to 1up. "The technology we got to demo was really impressive, and starting in early 2009, we began to think that it was time to bring it to games."
