I have 32' LG HD TV and a Sony PS3 Slim. I heard that Sony will have an update this Summer for the PS3, that will make PS3s compatible with 3D content. Will I need to buy a new TV to play 3D Blu-ray movies? How much will the 3D glasses cost me? I only want to watch movies in 3D, not cable. My model number TV is: 32LG30 Thank You!
