We can expect to move to higher resolutions rather shortly. The progression of technology is slightly disturbing if you look at it from a mathematical point of view. 50 years ago, the doubling rate of technology was over one hundred years. Huge advancements that no one could have ever predicted happened and the doubling rate of technology is currently 2 years. This means, in 2 years you can expect ALL of your current technology to be considered obsolete, by technical definition.
Japan is already saying they will broadcast every station in 8K by 2020. Sharp recently showcased an 80 inch 8K TV prototype while 16K resolution is already being worked on. The key in broadcasting and transmitting all of this ultra high definition content without lag will be super fast networks, meaning everyone will be making the switch to gigabit/fiberoptics probably by 2020. They are already working on DNA Computers (biochips) that are faster than all of the world's current super computers, theoretically capable of solving The Travelling Salesman problem in 3 seconds. Our current super computers need about 300 years to solve that problem. It is projected that by 2020, the doubling rate of technology will be about 18 months. It's just crazy.
