So that just begs the question – who does have one?
The snarky answer to that is ‘no one’ – but our man attests that developers have been allowed to see improved features that upgrade the device’s current capabilities.
Specifics include a speedier and enhanced interface with its successful Kinect controller that means the camera kit is more responsive.
Previous rumours have also said Microsoft has a new disc format to add to the machine.
Any company that has been granted access or ownership (temporary or otherwise) to such a devkit will be honour bound to deny it.
And third-party developers, both in-house and independent, will want as much access as possible to such devices to make sure they are ready for launch.
In fact, Develop knows of at least two franchises in Europe currently undergoing production with new consoles in mind – so a next generation is coming, whether publishers and console manufacturers want us to know about it or not.
