he is absolutely right but i'd like to propose one minor change.

"These months are small if you look at the sales. I think the whole month of June is about one week in November. They're winning, and they'll do their PR around it, and that makes sense.  The battle slaughter is really September, October, November, and December."

It's ok to want things.

Great games coming for Xbox in those months. It the system that gets my playtime.

The battle is already over.  He should stop talking about  overtaking the PS4 and start talking about the battle for second place.

My guess is if he is talking about WW, he is putting a lot of faith in those 2 tier countries with China and Japan

And they're going to get mauled in September.

Mauled in October, November and December globally too. Unless he is only talking about the US they will get mauled either way.

I think he was talking about globally in the US

He's right but PS4 will sell significantly more in those months too.

Guys relax, he only said that's when the battle not that the Xbox One will win it. Even though everyone knows this, it's bad PR and he probably isn't allowed to.
