No specifics other than a capacity of 300GB.

However, I remember BluRay supposedly being layered to get up to 200GB of capacity without changing the physical reading technology. Maybe they are just developing a standard for creating the media and altering firmware for readers/players. Of course, if the goal is to get 4K video into the home, then higher reading rates than current BluRay will be needed.
