Techradar.com: If Microsoft is secretly readying a new Xbox to succeed the Xbox 360, then surely Sony must be working on a PlayStation 4?
Speculation is rife that the next console battle will be fought around 2011-2012. This is when Crytek’s CEO Cevat Yerli and industry analyst Colin Sebastian believe that a potential Xbox 720 and PS4 could appear.
To imagine what a PS4 might be capable of we should look at what the current PS3 doesn’t have or doesn’t do well. For starters, Sony will need to closely integrate the hardware and software development for its next console.
According to SCEA’s CEO Jack Tretton: “The hardware guys developed the [PlayStation 3] fairly independently, then dumped it onto the software guy’s lap, effectively saying ‘do something with it.’”
If the PS4 is a revamp of the PS3, we’re likely to see some obvious technology upgrades – 802.11n to replace the existing 802.11b/g chipset; an external power supply (to reduce the size of the box and to improve cooling); a massive hard disk; new graphics processor and an increase in the onboard memory.
What about a replacement for the PS3′s NVIDIA-built RSX graphics processor? We’ve already speculated that Microsoft could use Intel’s general purpose Larrabee chip in its next Xbox to handle real-time physics and AI. Rumours also suggest that Intel is pimping Larrabee to Sony for the PS4.
