1. What do you really need to experience 3D in the home? Just a 3D capable TV? What about 3D capable receivers, blu-ray players, cables, content, accessories, etc?
3D TV, glasses and 3D BD player. You also will most likely need a receiver, but this one is more complicated for three reasons. 1) Sony, and others, said the PS3 will be a 3D player, so is 1.4 necessary? 2) 1.4 in the player and TV most likely means it is needed in the AVR if you pass through it, but is it necessary? 3) Panasonic showed a player that had two HDMI out one 1.4 for video and one 1.3 for the sound so that the 3D video does not need to pass through the receiver, so with that player a new receiver won't be needed.
As for cables the answer is no, as long as you are using HDMI now. And except for some mention of 3D TVs that can turn 2D into 3D, but obviously for real 3D you would want real 3D content.
