He also pointed to the memory limitations of the 32-bit versions of Windows as an example of how PS4 titles could even surpass what "most PCs" can do.

"I think it's a very smart move on Sony's behalf to build this sort of enhanced PC architecture and then put so much in it," he said.

"Let's not forget it has 16 times the memory we had in PlayStation 3 - that's not insignificant. Knowing that every machine has that... we can do crazy, ridiculous stuff with that.

"The other exciting thing is that... when you think about Windows, even Windows for most people is tied to about 2GB of addressable memory space. This really opens up beyond what most PCs can do, because most PCs are running a 32-bit version of Windows.

"It's like giving you the world's best PC," he added, pointing to Sony's introduction of "super convenient" features such as the ability to play games while they're downloading and perform background updates.

"The kind of stuff that they announced that they're doing, the level of convenience and things like that... they're making a really perfect gaming PC," he added.

"I've always said that the things in the next-generation that aren't just brute force hardware are all about the service and simplicity of the experience - the things that make it as fun and easy to get a PS4 game as it is to get a game on your iPad."

Commenting on Microsoft's next-gen console plans, Rein said he was confident the Xbox firm will also be doing something 'along the lines' of PS4.
