Large 3D LCD screen televisions would have to come down in price. This could be a marriage between the home computer and the 3D television set as-well as a marriage between the Internet and Cable TV.
Considering the amount technology that has been condensed to fit into mobile phones like the i-phone and such with Internet, two-way video transmitter and television set in the mobiles then the natural progression would be to evolve the flat-screen computer monitor into a 3D flat-screen television set that plugs in/bluetooths into the computer with the cable TV digital recorder/decoder. And when the mobile phone is connected to the computer and someone gives you a video-call the picture would display on the computers monitor and recorded on the computer external hard disk. One terabyte would be able to record 400 hours of 2D regular digital definition video.
