The batch of PS4 units that was made available on Amazon.com has now sold out. It took only 25 minutes.
On the other hand the batch of Xbox One offered at the same time is still available at the moment of this writing. Of course we don’t know the amount of units that were made available for each console, so it’s not possible to draw a direct comparison just by taking in account which one ran out of stock first.
That said, if you want a PS4 from Amazon, at least for now you’re out of luck. We’ll keep you posted if we see further batches popping up on Amazon or anywhere else.
Update: the Xbox One batch has run out as well. It took about seven hours.
