A slimmer PlayStation 4 wasn’t enough to slow down Microsoft’s momentum.

Xbox One was the top-selling home console in the United States September, according to data from industry-tracking firm The NPD Group. This marks the third straight month that Microsoft’s gaming system has beaten out the PlayStation 4 and Nintendo Wii U in terms of units sold. After winning July and August, Microsoft has strung together a strong few months. But it’s important to note that summer and early fall only do a fraction of the sales that the industry will see in October or especially November and December.

Microsoft has built up momentum coming out of the summer due in large part to aggressive price cuts and the introduction of the slimmer, sleeker Xbox One S hardware revision. Sony countered with a slimmed down revision of its own for the PS4 that debuted September 15 at $300. PlayStation fans, however, were likely saving their money for PSVR or the 4K-capable PlayStation 4 Pro system that is coming in November instead.
