I am sorry but using 4 months of data to make such claims is really flawed. Maybe you should wait a year before making such statements.

4 months of data is 100% of the both console in the market.

I just didn't put November in the OP because the launch preorders are post in the previous months in Amazon... so PS4 won every single month in 2013 but in November Xbone won when PS4 can't be more purchare at Amazon since September or August.

So after the preorder period... the sales are really reflected the ranking.
