That's always been the "problem" with 3D video. You have to put something on your head (or be inconvenienced in some way or another) to view it (until holographic projection becomes mainstream, with high quality at a low cost), so 3D video has always been a sort of niche/novelty type thing. The images can be acquired reasonably with current technology (that's been doable, and been done for a long time really, way back to the earlier part of the last century actually).
