While Sony proudly boasted earlier this month that it has sold an impressive 35.9 million PlayStation 4 units to date, Microsoft has been a little more tight-lipped about its own Xbox One sales figures.

But, gaming giant EA might have just accidentally revealed Microsoft's little secret. During a financial call last night, EA's CFO Blake Jorgensen said the company estimates a combined install base of consoles at around 55 million, according to Eurogamer, up from the 50-51 million he predicted for 2015 in November.

"Console purchases are up through the end of calendar year '15," Jorgensen said, according to a transcript. "Our estimate is 55 million units out there which has exceeded virtually everyone's forecast for the year and now almost 50 percent higher than previous console cycle so, all of that is very, very positive."

So, using our subtraction skills, we can surmise that Microsoft has sold somewhere around 19.1 million Xbox One units to date. Redmond hasn't really talked about consoles sales since November 2014, when it revealed that Xbox One was approaching 10 million sold. An Xbox spokesperson did not immediately respond to a request for comment.

Microsoft reported its financial results for the fourth quarter of 2015 last night, which included a 9 percent year-on-year drop in hardware revenue, primarily attributed to a decrease in Xbox 360 sales. The company also saw a slight drop in Xbox One revenue during the quarter, despite an increase in sales, due to the console's lower price during the holidays. On a more positive note, however, Microsoft said revenue from its games business increased 5 percent this year and Xbox Live users grew 30 percent.
