Sony and all other TV manufacturers will start pushing glasses-less 3D TVs when the tech is efficient and affordable enough to be pushed into our living room in sizes over 3.5 inches (or sizes big enough to allow multiple viewers to look at the thing without getting a blurry picture).
Right now, the best reports I've got about the current prototypes is that the viewing angle is of 30 degrees. That's really not the kind of tech that can work in your living room with multiple viewers. That is why the technology is better suited for portable devices at this point in time. It wil get better down the road, but in its current form, it's just no good for a crowded living room.
