Personally for me, evidence seems to suggest Satya was a big reason for this shift and not being in 3rd place. They were 2nd place for quite a long time, and I don't think NSW devices has surpass gross XBO sales yet in 5 months.
Who runs the Xbox division? It's that smug T-shirt guy right? I'm sure the terrible $499 launch and subsequent lackluster sales had nothing to do with the sudden generosity of the division to become interested in the gamer's well being after creating the walled off garden online model last gen... Just wait, next gen MS can be #1 and stop playing nice, then Sony can whine about why everyone is not cross-platform.
