An anonymous reader writes with this excerpt from Eurogamer:
"Microsoft is ramping up development of its next generation Xbox console according to job positions being advertised on business networking site LinkedIn, brought to light on the Beyond 3D Forum. The first position advertised is for a Graphics Hardware Architect, working with the team that is 'responsible for defining and delivering next-generation console architectures from conception through implementation.' 'The responsibilities include architecture analysis, key technology selection, architecture specification, communication and collaboration with extended Microsoft teams and partner companies,' according to the advert. ... the most intriguing element of the story is just how early on in production we appear to be — far earlier than many had suspected. Unless Microsoft is actually planning pre-production of the next next-gen console, the evidence seems to suggest that the system is so early in development that the graphics hardware at the very least hasn't been locked down."
