Those were announced too. Panasonic showed off a 4K OLED TV. But would you buy one without an interconnect standard defined to handle it, no disc format standard (Sony says they'll make 4K Blu Rays, but who knows if it will require a whole new player) and no way to certify a display as fully UHD compliant right now (you have to have at least one digital input capable of accepting a 4k signal, which doesn't even exist yet)? You're basically hoping those things will work and buying it for the upconverting. What if, by the time all this stuff is decided, 8K TVs start coming around?
