Probably got fed up of Pro 

Looks like the Black Ops bundle is going to be sold out for a bit. It says there are only 18 left. 

They'll either restock immediately or turn it over to third parties until they can restock, unless this is the last of the stock, in which case we should see the PS4s rising.

As soon as Sony announces that Infinte Warfare bundle for the US, slim sales will take off.  They'll likely lose October becasue pre-orders will definitely eat UC4 bundle sales. 

But PSVR could offset that. I'm still inclined to think the PS4 edges Oct. It's Gears month and I'm certain Sony will have something else up their sleeves too. They won't want to devalue their console like MS have but I can see them offering an extra game or two as an incentive.

IDK I'd be surprised if  PS4 Pro and inevitable Infinite Warfare pre-orders for October didn't hurt there chances of pulling off October NPD. I think XB1 might edge out the win.  Gears 4 will move some units, not as much as Halo, but it will. I also wouldn't be surprised if Microsoft has some kind of promotion every month until February. Especially if retailers still have OG XB1 stock. 

We'll see, but we mustn't forget it's MS that have to prove themselves, not Sony. They won two months. One based on offering crazy deals (won by 10k) and the other because of preorders of the slim. Sony have been winning this month and only ONE XB1 bundle which has 5 games and an extra game has managed to pass them. I'm not saying you're wrong, just that I wouldn't want to call October just yet. And just to add, the Gears bundle has rarely been in the top 100 with only a couple of weeks til launch.
