Microsoft is going to launch its first ever game console with a built-in Blu-ray player. The much Xbox One will have a Blu-ray player but you will not be able to playback 3D Blu-ray movies on the new Xbox One. One Microsoft official confirmed CNet that "the Xbox One doesn't support playback of 3D Blu-rays, though the company hadn't ruled out adding the feature in the future."
Microsoft thinks that 3D Blue Ray playback support feature is not that important to be available at launch. Microsoft Director of Xbox Programming has announced back in May to add 3D and 4K output on the Xbox One but the company is not doing this initially. However, tech giant can add this feature later via an update.
On the other hand, Sony has confirmed that PS4 will surely support 3D Blu-ray playback and 3D gameplay as described in its official FAQ. But both of these features might not be available at launch. The Japanese giant is also considering adding support for 4K still images to PS4 in future. Sony's PS3 is already supporting 3D games and 3D Blu-ray movies. And just after a week at launch of PS on November 15th, we will clearly know what it will have in it. Xbox One is scheduled to launch a week later on November 22.
