If you have your eyes opened, this should not be a surprise. The only reason I bought a 3D set is because you have to if you want choice, ones without it are not numerous, and rarely are top end. 3D Blu-ray players are stacked high and wide at the stores, at least in Ct. when I went TV shopping. Sales are so bad the newest LG 3D Blu Ray player with Wifi was briefly at $139 when they hit the stores, and Best-Buy dropped the price to $114, less if you bought it at the same time as a TV.

The relevant fact here is that 3D blu ray sales are so low, because no one is buying 3D players. All the manufacturers have to find a way to sell everything that is 3D at the same cost as 2D to keep the media alive. But even then the economy is preventing any bust out of sales.
I'm not quite convinced it's all doom however. The economy being so bad, has to be hurting 3D, most people are not going to buy a 3D player if they already have a good blu-ray player, or even a good DVD player. If 3D can make it to a better economy and not be more expensive than 2D there is hope.
Also, there is some 3D available online that smart apps on a TV can stream, most notably movies from Vudu, and LG has it's own 3D shorts. Combine that with 2D to 3D, which makes anything into 3D(ish) and maybe there will be more interest. I actually find 2D to 3D on the LG with passive technology not bad for some shows. Once you learn to get the best setting it really is approximating 3D, though not to where something comes out of the screen at you. In particular Ice Road Truckers really does benefit from 2D to 3D. To my eyes when the scenes are outdoors is when 2D to 3D seems to work the best.
That said however, for me it's still not must have, more fun to use sometimes.
