Wow, huge Xbox One NA numbers. That's insane! Should be a good generation for both consoles.
The gap is already over 6 million, you think the gap will only grow another 4 million over 7 years? Of this I am certain, there is no way both Xb one and PS4 are coming close to PS3 and 360 numbers this generation.
There was zero growth between gen 6 and gen 7 across the PS and Xb platforms (PS2box = 181M, PS360=167M). All that happened was a reshuffling of market share towards 360, and the missing 14 million are those who went with Wii instead. I also think the casuals of the last 2 generations have gone to the real casual platforms of phone and tablet, and facebook games. So PS4 and Xb one I reckon are fighting over a market of about 150-160M. My guess is best result for Xb one is 2:1 split of market share in favour of PS4 with 100M:50M.
