4K was the point of diminishing returns, human perception isn't capable of distinguishing anything more than 4000 divisions across in their field of vision. Higher resolution than that is only useful if you're going to be blowing the image up or just looking at a small section of the image, which by definition is NOT the video-watching audience. Also, eventually people will realize that pushing 4 times as many bits down the pipe costs 4 times as much. Flat panels will transition from LED to OLED as the yields get better, currently a 65 inch OLED costs $5000, and larger ones go up to $20,000. Smart TVs already have WiFi and Ethernet support, and yes, even web browsers, as well as all the popular streaming services built in (although using a TV remote as a mouse really sucks). A few smart TVs even have voice command support, that that has sparked privacy concerns -- can you really trust your TV when it's listening to everything in your house 25/7? (Sounds like a Big Brother scenario to me). Yes, I'm still waiting for videoconferencing to be built-in to the TV, or at least support for a USB webcam. Not sure what the killer application for motion detectors is; even Kinect seems to be fading now, despite my initial reaction that they could build some great games around gesture recognition.
