That´s only my theory. XOne has been siting on lower 20s for a week now and PS4 droped to lower 30s.

When there was no stock PS4 and XOne droped to mid 20s, even with it being in stock, when PS4 went back to stock both consoles went up.

Never happened that PS4 was on top and XOne at 30th. Xone was always 5 to 7 position behind but when PS4 sold out, both droped.

Any way, how Amazon calculate their best sellers is a little mistery.

Every time Amazon got PS4 new shipment the console was number 1... some times the Xbone didn't even reached the TOP20.

Right now for January 2014:

4. PS4
16. Xbone

PS4 will go to number 1 in matter of hours again.

There is no mistery... just sales.

Wonder what dark feanor will say when ps4 outsells x1 in the US again this month LOL. Grab your popcorn.

Well, this list hasn´t move in the last week since PS4 has droped havely in the "hour to hour" bestseller list.

And I suspect they count second party retailer sales.

"Again"?? Y

You mean 3 weeks out of 8 PS4 outsould Xone??

Well, may be I will cry like a little girl.

Last time I checked PS4 outsold Xbone in US by over 150k... January will increase this number.

US = PS4 Land.

LOL, ps4 is ahead because when it got stock it sold a lot more then x1....so your WEEKS argument makes no sense.  Supply and demand look it up./

Again yes ps4 outsold x1 in the biggest month of the year..november.

With one extra week.

LMAO that made zero difference...............PS4 did 1 million in 24 hours...x1 600k...................That extra week never made it up not close, x1 did 900k in 3 weeks, again way behind ps4's 1 million in 24 hours.... keep reaching.

You can align the launch but it won't change the facts... PS4 will be ahead yet.
