As part of its investor call after its quarterly earnings report today, EA CFO Blake Jorgensen revealed that the combined install base for the PlayStation 4 and Xbox One is over 55 million.
That number strongly implies that the install base for the Xbox One is around - or just over - 19 million units. We can deduce this number from the fact that Sony reported this month that it has sold nearly 36 million units of its PlayStation 4.
This news lends credence to a report we saw earlier that 18 million Xbox Ones were active and online, which was culled from the greater pool of Windows 10 activation numbers. The system's OS was moved to Windows 10 in November 2015.
Microsoft, for its part, has said it will no longer report install base numbers for its consoles.
It did, however, report other stats on its console ecosystem today, including Xbox Live user numbers and revenues.
As of September 30 last year -- the most recent numbers available -- Nintendo's install base for the Wii U had hit 10.73 million units.
