Playstation 4 may use AMD A10 APU

VG24 has an interesting tidbit regarding the next Playstation. They are reporting that development kits for Sony’s PlayStation 4 code-named “Orbis”) have been sent out to developers as a "modified PC". This new Playstation seams to have some interesting internals going on.
Apparently this dev kit is based on the AMD A10 APU and will run games in 1080p resolution at 60 frames per second in 3D. These developments kits are rumoured to have between 8GB-16GB of ram, 256GB of storage, no word if this is and SSD or standard Hard drive, Blu-ray, and the standard inputs and outputs found on the PlayStation 3 with HDMI, Ethernet and Wi-Fi.

interesting, one would assume they would go with RISC or ARM
