PlayStation 4 is believed to have edged ahead of Xbox One in the US during the very early stage of the battle, but the race remains too close to call, Baird Equity Research analyst Colin Sebastian has claimed.
"Sony's PS4 clearly bounced back from our mixed early-2013 supply chain checks, and appears to have a slight momentum edge among core gamers, as demonstrated by premium prices on eBay and persistent out-of-stock reports at retail," wrote Sebastian.
"However, we view the console battle as too close to call, with both platforms selling well over the holidays. Moreover, a competitive 'two horse' console race would be positive for software publishers and retailers if Microsoft and Sony are forced to compete aggressively for market share."
Both the PS4 and Xbox One have sold more than two million units worldwide.
