A supposed industry insider over at the Seattle Post is claiming that Microsoft is moving the standard Xbox 360 hard drive size to a more reasonable 60GB, with the configuration already in “design verification testing.”

And it’s confirmed 100% that the HD (hard drive) is moving to 60g standard. Those configurations are in design verification testing right now. I’d bet that this changeover also contributed to the lack of units. When MS changes major sub-assemblies like this, they try not to over produce the old configurations.

The source also shed light on Microsoft’s recent case of supply constraints with the Xbox 360, noting that the constraints in question were a result of “poor planning, supply chain and quality issues.”
