I'm probably being short-sighted, but I fail to see what else could you add to a TV that you couldn't already by attaching some device to it.. it's like saying Jobs will revolutionize the computer monitor. It's just a display.
To try to give you some context, think back to 2005, and question 'how can you revolutionize a phone? It's just a speaker and a microphone'. Of course, there had already been inroads into making your phone much more than a phone, just as set-top boxes and other connected devices have added capabilities to your television.
I don't think we'll see a 'rebirth' of television so much as we'll see television joining mobile, tablets and computers in the middle.
Really, the revolution of the phone was making it more like a computer, but more portable. The revolution of the television I suspect will be the same, but less portable. Just like the portability of the phone expanded the things we used our phones for, a less portable large screen product could expose similar capabilities.
