In response to a question regarding whether the new console will include these features Hryb stated "XBOX ONE supports both 3-D and 4K, including 4K for Blu-Ray."
In regards to 4K adoption it is not without its hurdles. Sony Electronics in February stated that 4K videos require downloads over 100GB in file size. Whoa! That's a huge file. Considering the XBOX ONE comes with 500 GB of internal storage, that would mean about 5 4K movies could be stored on the device at that size. Also, internet speeds are not yet fast enough to speedily get 100 GB quickly when downloading.
While Sony's Playstation 4 (PS4) will support 4K output for photos and videos, it will not support 4K games. Microsoft has confirmed that XBOX ONE games will support both native 4K and upscaling to 4K.
