Looks like 4K is the new 3D. Since 3D has not caught on in the home like everyone thought it was, it's now the content makers like Netflix that are supplying the go-to technology of the multimedia future. Streaming 4K is going to be widely available, and it looks like optical discs are going to be left out of the loop, at least for now. 4K TVs are becoming affordable (sub $1k), and Netflix is the medium that will be delivering it most of it. Already some shows are filmed and available in 4k.
