It would take in-depth analyses and comparisons between the features of the PS4 vs Xbox One to know which of the two game consoles is better. Other factors such as the price and the demographic profiles of the gamers should also be taken into consideration to understand the comparative 2015 sales performance of the two game consoles.

As the year came to a close, the holiday season was likely to trigger the shopping frenzy of consumers. Year-end bonuses from work and the discounted prices are primary reasons for the traditional increase in consumption during the holidays.

Marketing strategies for various consumer products, such as the two gaming consoles, also likely influenced the purchasing behavior of buyers.

On one hand, recent retroactive compatibility updates by Microsoft for the Xbox One Wireless Adapter is one of the reasons for the increase in popularity of the game console. Microsoft also resorted to lowering the price of its game console.

On the other hand, Sony focused more on exclusive games and better graphics. Sony has significantly increased its PS4 sales.

The game console proved to be more popular among the early adopters of the current generation game consoles. Based on the most recent sales statistics, Sony's PlayStation 4 is also currently outcompeting Microsoft's Xbox One.

The sales ratio is two-to-one with more than 22.3 million PlayStation 4 units confirmed to have been sold globally. By comparison, Microsoft's Xbox One had a total of 12.8 million global sales. This trend is likely to continue as the price of PlayStation 4 drops.
