The company has confirmed a 4K movie service will be available on the PS4, but told The Verge that the size of super-hi-def movies could be upwards of 100GB.However, Sony Electronics president Phil Molyneux, told the Verge in late February that these were "challenges that we have to work through... we've got some very good ideas that will make that a comfortable consumer experience".
One standout feature of the PlayStation 4 is that it can download content in the background, or even while the system is switched to stand-by mode, which could be adopted as a possible solution to downloading large files.
"But what I'm really more interested in is other ways of expanding into the next generation - a more horizontal expansion, where you're going to be doing things online, more of a social aspect. People will be able to interact with the game through various devices, through various media - such as tablets, smart phones, etc."
Kojima teased that these various gameplay experiences could eventually find their way to the Metal Gear franchise.
"I think it's this new type of interaction - this new way of interacting with the game world - that's more exciting to me. And I want to bring the Metal Gear franchise into that new wider world of interaction."
