Does anyone else think UHD Blu-ray is one step forward, one step back? This shit is ridiculous. There is no good technical reason for why the format couldn't have supported frame packed 4K 3D video @ 30 Hz, since it supports 4K 2D video @ 60 Hz.
Already, I'm finding myself having to decide between whether I want to watch a movie at a higher resolution in 2D or watch it in 3D, when my Samsung JS9500 Series 4K TV
could support 3D video at 4K resolution, if only the crappy UHD Blu-ray format supported it. I think it's reprehensible that they left 3D support out of UHD BD's technical specifications because now they are going to force us to choose between the 3D Blu-ray or the UHD Blu-ray for every future 3D movie.
M-Go has several titles in 4K that have a 3D Blu-ray release like Life of Pi and X-Men so it's already happening even though UHD Blu-ray isn't out yet:

Sony's Video Unlimited 4K service also has several movies that have a 3D Blu-ray release, but their 4K release is only available in 2D, like Men in Black 3, The Amazing Spider-Man, The Amazing Spider-Man 2, etc.
This situation of having to pick between watching a movie in 4K or in 3D instead of being able to have both at the same time is completely unacceptable.
