Another piece regarding PS4 and its rumored specs and controller has gone up on Kotaku, which has culled information on Orbis from a 90-page PDF document included with development kits.
According to the report, the developer kits contain 8GB of system memory, 2.2GB of video memory, a 4x Dual-Core AMD64 "Bulldozer" CPU - which gives it 8 cores, an AMD R10xx GPU,
a Blue-ray drive, 160GB HDD, and 4x USB 3.0 and 2x Ethernet ports. The audio output is HDMI & Optical, 2.0, 5.1 & 7.1 channels.
Again, these specs are not confirmed nor are they final, if this is indeed a developer console.
The system at present supports both the Sixaxis and DualShock 3 controllers, but there is a new one in development as well, according to the documents.
Called the "Orbis Development Tool", at present, it still sports the four face buttons, two thumbsticks and shoulder triggers, but contains a capacitive touch pad similar to the one of the back of Vita. It can discern two-point multi-touch and it can also be "clicked" for use as an additional input button.
It will also contain motion-sensing like previous controllers, but tilt correction has been improved. It also still contains vibration, and an RGB LED light. No mention of "biometric" technology was made in the documents, a feature which was rumored over the weekend.
There is also a "Share" button on the controller which Kotaku figures will allow users to share various gameplay activities via social networking sites or possibly work as a screenshot button.
However, it may have something to do with a change to the way user accounts are managed. With PS4, Sony is supposedly implementing "multi-user simultaneous logins." This will allow more than one user to log into the console at once, linking the user account to the controller.
As the controller syncs, the player will be logged into the PS4 currently in use. Accounts won't be "locked" to the controller, instead users will be prompted to sign in their account when an extra controller is detected.
This will make things rather easy when you go to friend's house, plus, the purported documents claim four can be in use at a time, allowing all co-op players to receive trophies together locally. It's unknown if this will work using PSN as well.
