From January 2nd to January 16th last year, the PS4 sold 109k in the United States and the XB1 sold 63k in the United States.
Assuming similar sales this year, and assuming Amazon is an average retailer, that would mean preorders are probably greater than 109k after one day.
That's not a very high benchmark to pass. Obviously sales could be much higher than the ps4, but all we really know is that it has outsold the best selling ps4 sku on Amazon. By how much is anyone's guess.
