It's been a long time coming, but specs for both of the major next-gen games consoles, the Sony PS4 and the Xbox 720, have been leaked. And they're both based on pure AMD technology.Before we deep dive into the details, is the leaked information accurate? One can never be sure. But the signs are good. First, it checks out in terms of plausibility. The hardware is based on known and realistic tech. The information is detailed, particularly that revealed by vgleaks.com a few days ago. And it makes sense.
