You know what's fun? Literally anything that isn't combing through dozens of Microsoft job listings in search of telling phrases such as "next generation Xbox". Still, every now and then I just can't help myself, and every now and then, the effort proves worthwhile.
For instance: we now have something in the way of official confirmation that the next Xbox will utilise the x86 processing architecture rather than Xbox 360's PowerPC setup, as rumoured. Microsoft is seeking a software development engineer to work on Xbox 360 and Xbox Live, see, and experience with the x86 architecture is "desirable". Conclusive. Well, it is if you squint.
A good time, perhaps, to revisit this supposed next gen Xbox specs breakdown. Alternatively, you might give a little more thought to whether you really want the next Xbox to be backwards compatible - the choice of an x86 architecture makes this rather less likely.
