Sony XBR-X850B

In the future, every TV will be like the X850B – a 4K TV, with four times the resolution of the majority of today's HD displays. So consider this 64.5-in. Sony model a sneak peek of just how impossibly crisp and vibrant home theater will be, as well as a future-proofed set that will properly display all of the higher-resolution content to come (including streaming 4K video already available from Netflix). It's also packed with forward-looking features, like the ability to play PlayStation 3 games without the console – all you need is a Wifi connection, and a game controller. [$4000; store.sony.com]
