Thats not true, PS4 1TB is also in stock and Uncharted 4 Bundle is in stock, so basicly you have 3 bundles in stock and only one sold out. And point same in any case, PS4 is not sold out, that BF SKU was just PS4 1TB model with just lower price tag, you have same that PS4 model on Amazon but for higher price point availible.
The PS4 1TB was out of stock and only available on the 26th when I checked. I guess it got re-stocked. The Uncharted 4 Bundle is discontinued and being sold at higher than RRP by a third party.
Edit: 2 seconds later and the 1TB PS4 is out of stock. It said available on the 28th of Nov.
