At first I wanted to say 3D but that has been done in movies and on TV and is still not all that popular, even in theaters.
So, I beleive the next major paradigm shift in TV is the true seamless integration of bidirectional TV, ie one in which you can pick and choose your programming at will from the entire database of existence. Simply say out loud, TV, bring up, Gone With The Wind, or GhostBusters and the home theater system will simply go to the database via satellite or cable and begin to play that movie. Or, you could say, TV bring up the list of Star Trek movies and then select the ones you want to watch in succession for the evening, including HDTV if available. All this for your choice of either PPV or monthly subscription to genre's of databases.
You could even take this to Sports. Simply say, TV, Please timeshift the Superbowl from 1998 to tonight at 7PM. You could get this instant replay of that event when you want.
The technology is here today, just that it is not yet widely implemented at this time. Companies like SeaChange and Hewlett Packard will be making all this possible. The only link needed is an internet integration for ordering up and then a way to bill it. The voice recognition technology is also here but not yet integrated into your TV and Home Theater, except for some nerds who have tried this on an experimental basis with their HTPC's.
All this, I see hapening as a result of marrying the different emerging existing technologies in one center
3D, Holodecks, etc. ? No, not in my lifetime. Might as well wish for direct brain implant of the memory of having have seen the movie.
Interactive TV is another and this is already being done on CD game roms. The video changes as you play the game. You could have games on broadcast TV the same way once high speed internet is a reality everywhere.
