Eh. This is microsofts strongest month in their strongest territory and they have all this momentum from the xb1s. They basically just hit a wall running, now that the Pro is out. The paradigm will return back to normal at the very least until Scorpio comes out moving forward. What are you gonna say when ps4 takes the next 9+ NPDs in a row?
Xbox took 4 of the last 5. PS4 only won November because of pro launch. Xbox should be able to take at least some months.
So if the PS4 only won November because of the Pro, what do you think helped the X1 win some of those months? It's not it like the X1 was just coasting along and took 4 months.
