Even though it sounds like Sony eeked out a victory, it looks to me like XBox has made serious inroads against the PS4.

XBox was the only system that was up year over year (meaning Sony was down over last year even with PS4 Pro and PS4 Slim and $250 PS4) and overall outsold the PS4 for the second half of the year (after XBOne S was launched).

That's impressive for Microsoft.

Well Halo Wars 2 and SoD2 are pretty big IPs.

The CGI master race 😀

I just got in, did Sony not win December? 

Sounds like they are down year over year though, whereas MS is up year over year for December. That means they closed the gap. To be honest Sony should be blowing MS away and be way up this year with a new model, a new redesign, and $250 ... it seems to me like MS is seriously slowing the PS4 down in the US by becoming more competetive. 

It's common sense that a new product sells more than old products when they first hit the market. Switch isn't competing with PS4 or Xbox just like the Wii since both were not targeting the same consumer. No one who doesn't buy an Xbox is going to buy Switch, just as no one who doesn't buy a PS4 is going to buy Switch. They will buy they other instead. Switch is irrelevant to the other two and has it's own lane with no competition except the 3DS ironically. So Switch sales won't be at the expense of the others. I expect the sales to be lower than Nintendo fans expect since it is not releasing in the fall and there isn't much hype compared to the WiiU. Nothing like when the Wii was coming.

It down but we dont know how much so its to soon to say its bad for Sony especially when last years lineup of bundles and games were better than this year.

I guess global sales don't exist on this site?

Is there any wonder some of Microsoft's fans are shameless?

Agreed, Switch doesn't factor much into the console side at all (not in the US). Both Sony and MS being strong here is bad for Nintendo too because there's less room to sneak in with two already established competitors with long head starts and established momentum. 

Switch's main competetion is the 3DS, agreed. 

Remember, Microsoft had a very clever release schedule for its XB1S bundles, either releasing them at the beginning of a month or almost the end of it. Release a bundle at the beginning of the month gives the XB1 an early boost and a late month release gives it a last moment push before the NPD period ends.

Also, the Minecraft bundle was further discounted from Dec. 11 to 24, so during those two weeks, the XB1 had the advantage of having the cheapest SKU in the market. This is a significant detail to point out because holiday sales are dictated by price more than anything. Now, the PS4 and XB1 are at price parity. In addition, the PS4 has much better software support for the first months of 2017. Lastly, in 2015 and 2016, the XB1 exhibited larger December to January drops than the PS4.

Sony definitely has reason to be worried. With the release of the PSVR, PS4Pro, the new Slim and $250 (temporary) it's still down YoY. But what has to worry Sony the most is that ever since the XB1s has been released the XB1 has outselled the PS4. You can call that a spin if you'd like but it's simply a fact. Hopefully we'll see YoY growth next month for the PS4.
