VG247 has learned that Microsoft has now detailed Xbox 720 to certain partners and has internally confirmed the machine for a Christmas 2013 release.
The next generation Xbox will have a Blu-ray drive, contrary to a recent report. Multiple sources have confirmed this morning that the machine will have two GPUs. One said: It's like two PCs taped together.
We're waiting for final confirmation of specs, but the graphics cards are thought to be equivalent to AMD's 7000 series GPUs, but "not CrossFire or SLI". The GPUs aren't structured as they are in a normal dual PC set-up, in which the two chips take it in turns to draw lines of the same object: Xbox 720's graphics units will be able to work independently, drawing separate items simultaneously.
There will be "four or six" cores to the Xbox 720 CPU, one of which will be reserved for Kinect and one for the OS. Xbox 720 will require an always-on internet connection as an anti-piracy measure. We've also been told that the next generation of Kinect will be built into the device as standard.
