It is sold out at SOME retailers around the world. Some retailers here are out of stock and are taking orders for the second shipment, which has not arrived yet, other retailers still have Xb one in stock.

Of course this once again rears the topic of yeild issues. Xb one shipped to fewer countries with lower sales to consumers compared to PS4 yet is short of stock. Perhaps the factories have lower production capacity compared to PS4 and it's not yield per se that is the reason for Xb one shipping fewer units than PS4.
