Despite the hype of its "Avatar"-fueled launch and accompanying predictions about a proliferation of made-in-3D movies, sports, and TV shows, 3D is still uncommon today. There's not much actual 3D you can watch on a 3D TV. With a couple hundred total Blu-ray titles available now, that format is by far the best 3D source, but selection is still slim compared with the thousands of 2D Blu-ray titles. Beyond that, most games are 2D-only, on-demand 3D sources available via streaming or your cable/satellite provider are scarce, and the few true 3D TV channels are fading fast. Do they worth the extra cost now or rather stay with ordinary traditional pictures?
