UPDATE: The original document, which had been posted to sharing site scribd, was taken down over the weekend “at the request of Covington & Burling LLP,” a major IP law firm that represents Microsoft. While the move doesn’t positively confirm that the document is genuine, it does heavily suggest that Microsoft is taking action to suppress confidential internal information.
ORIGINAL STORY: Some fans and observers have expressed disappointment that Microsoft didn’t even bother to mention the follow-up to the Xbox 360 at this year’s E3. Those people should be much less disappointed by a newly leaked planning document, which details an “Xbox 720” that will include an improved Kinect, a head-mounted “glasses” display, and a major investment in cloud gaming.
The 56-page document, which started circulating widely this morning (and has since been taken down, see update above), purportedly represents a road map for the future of the Xbox platform through 2015. The document seems to date back to a mid-2010 internal planning meeting, and is focused on how Microsoft will sell the next Xbox’s new features to consumers, developers and other relevant parties. Microsoft is supposedly targeting a 2013 holiday season launch for the system in a $299 bundle with new Kinect hardware (more on that below), and plans to sell 100 million units during the console’s ten-year lifecycle.
(It’s important to note that we haven’t been able to prove the authenticity of this document, or source it directly to anyone inside Microsoft. We discuss whether the information in this document can be trusted further below.)
The “Xbox 720” described in the planning document will be six to eight times more powerful than the Xbox 360 (depending on where you look in the document). A vague “snapshot” of the Yukon architecture for the system shows a core application architecture featuring six to eight 2Ghz ARM/x86 cores, with two additional ARM/x86 cores powering the system OS and three PowerPC cores handling backward-compatibility functions. The document strongly suggests that this base hardware will be available in multiple configurations with different feature sets, with the architecture “designed to be scalable in frequency/number of cores,” and a “modular design to facilitate SKU updates later in lifecycle.”
