People just do not care about 3D that much. The numbers at the movies tell us so (outside of Avatar).
Now let's compare how many theaters are set up for 3D and how many are strictly 2D. From that standpoint, 3D is doing amazingly well, and is still very profitable. Hence the reason for at least 40 movies being released next year in 3D. I was a hater, but now I'm a lover. Bring on the 3D!!!!
