What happened to the stereoscopic gaming revolution?

If you surveyed the video game industry just after E3 2010, you’d think stereoscopic 3D had finally reached a tipping point and was on the cusp of becoming a new gaming standard. Sony made everyone attending its E3 press conference that year wear 3D glasses to check out big-screen trailers for titles like Killzone 3 and Gran Turismo 5, Nintendo unleashed an army of booth babes at its own press conference to show off the glasses-free 3D of its Nintendo 3DS for the first time, and NVIDIA continued to push its all-in-one 3D Vision system, launched the year before.
