All sorts of things are coming up, like the launch in China and further countries such as Russia, the Halo master collection and a strong holiday line up. So what weeks do you thing XBO will outsell the PS4?

The only time I could see the X1 outselling the PS4 globally would be a Halo 5 release week and the week after that ...

Halo5 likley, even doubt gears now.
otherwise nope never short of temp massive price cut bumps.

Halo 5 no doubt... Even though Halo Master Chief collection is a great deal, I dont think its enough tbh

When Halo 5 resaled.

1TB White Xbox One w/ white controller + Sunset Overdrive bundled and later Halo MCC for $399.

believe.

Every now and then in the US.
Never globally.

It will be hard to tell even when it does, because those weeks are unlikely to translate into a monthly win.

It's possible that during the $399 SKU week, XB1 might have already outsold PS4 for that week, but due to that being a massive bubble built up from delayed May sales, was then obviously outsold the rest of the month after that temporary effect was over.

Halo 5s release is the only time I think it can outsell it. In the USA I think it can outsell the PS4 in the weeks big exclusives like Quatum Break release.

never :)
