If you are looking for a new toy to spend your money on this Christmas, well happy day! It's expected that Ultra HD Blu-ray discs and players should be popping up around that time of year. UHD Blu-ray supports the 4K format - the "more better" HD. Instead of the measly 1920x1080 resolution of "conventional" HD video, we will get 3840x2160, and you can give that 4K TV set a proper work out at last.
You are welcome.
