They went from dominating in the 360 era (when Sony fumbled the PS3, and Nintendo switched directions to the Wii) to two generations of poorly received releases and being in third place. That’s even if you filter by the specific markets they dominated in with the 360.
And what are they focused on now? Windows gaming and cloud services. Their two core competencies.
And why? The people behind the original Xbox and 360 vision left. When you have no vision leaders in the company you fall back to what you know. In their case: windows and cloud services.
