Microsoft has surpassed the 2 million mark with their Xbox One sales.

The tech company has officially sold more than 2 million consoles since its launch on Nov. 22, according to Reuters.  However, while it took Microsoft 18 days to surpass the 2 million mark, Sony's PlayStation 4 crossed sold that many in 15 days. 

"The PS4 is currently available in 32 countries to the Xbox One's 13, though, and both console makers stress that they are selling practically every unit they can put into the retail channel, regardless of the raw numbers," Ars Technica reported.

Microsoft VP of Strategy and Marketing Yusuf Mehdi stated, "Demand is exceeding supply in our 13 launch markets and Xbox One is sold out at most retailers."

The Xbox One is priced at $499, while the PS4 is selling for $399.  Both next-gen consoles have improved graphics and better processors, resulting in higher-quality gameplay than ever before.

"Robert W. Baird & Co analyst Colin Sebastian in October said he expected shipments of 2.5 million to 3 million consoles for both the Xbox One and PS4 in October-December," Reuters reported.

However, Ars Technica explained high volume of sales during the holiday launch doesn't mean the numbers will be there in 2014.

"The raw numbers are higher than ever this time around, and it's a good sign for console gaming that people still seem eager to upgrade seven or eight years after the last generation's major console launches," Ars Technica reported.  "But if history is any guide, a speedy launch doesn't guarantee either system will be able to maintain its record sales pace even through next year."

According to Ars Technica, a "significant separation" in sales numbers between the consoles won't be seen until spring 2014.
