The PS5 will include a disc drive for physical games and 4K Blu-rays.
PS5 discs will have a capacity of 100 GB.
Game installation is mandatory, but the console will allow you to just install a multiplayer campaign, for example, or install the entire game and then delete the single-player portion once you're done.
The controller "doesn't have a name yet," but contains an improved speaker, USB-C connectivity, and a larger-capacity battery.
"There is ray-tracing acceleration in the GPU hardware," says Mark Cerny, lead system architect.
The new UI will allow you to see more details on what you can play at any time, as well as more on what your friends are doing.
Bluepoint Games, the studio behind remakes such as Shadow of the Colossus and Uncharted: The Nathan Drake Collection, is working on a PS5 game that it says is a "big" one.
