It could make some sense, then again it really doesn't. Here is my own simple math.
XB1 has sold a total of 5M+ in NA, its strongest territory. And at worst 4M in ROW. So basically 80% of its sales in NA = sales outside NA.
PS4 is dominant in ROW, and has shown to outsell the XB1 by as much as 2-8:1 in different territories. If we are being conservative and assume that the PS4 has only outsold the XB1 by only 2:1 in ROW then that puts the PS4 sales in ROW at ~8M. 5.6M+8M gives us 13.6M.
Now being that as of sept end, 13.5M PS4s were shipped, its kinda hard to believe that between sept and now, practically only 100k PS4s were sold. Especially when 800k PS4s were sold in november alone.
So to be realistic, its safe to assume that the PS4 is outselling the XB1 by at least 3:1 in ROW. which will put the PS4 ROW sales at around 12M. 12M + 5.6M= 17.6M. So my guess is that at worst the PS4 is at 16.5M to 17M as of right now or more. No way its less than that, or not the math just doesn't ad up.
