The press shot above doesn't do the television justice. Sharp says that its new display offers over two times the screen area of a 55-inch television, which seems impossible until you see in person just how big the new display actually is.
As for price, the 80-inch display is a predictably steep $5,499. You can pick one up this October, though considering that its 131 pounds, you may want to bring a friend or two.
Update: The press shot below gives a good idea of the display's scale.
