Sony has begun development on the PlayStation 4, with the games giant confirming that work on the console was already underway.
In Sony's year-on-year results of its Networked Products & Services division – which comprises the PlayStation brand and PCs – Sony hinted that it was working on the PlayStation 4 but would not give any more details.

PlayStation 4 plans
"For the home equipment the PS3 still has a product life," said Sony's Masaru Kato.
"But this is a platform business, so for the future platform – when we'll be introducing what product, I cannot discuss – but our development work is already under way, so the costs are incurred there."
Kato also explained that some cost-cutting will happen with the development of the PS4.
Speaking to investors, he said: "It is no longer thinkable to have a huge initial financial investment like that of the PS3."
