We are just months away from celebrating the fourth anniversary of the PlayStation 4 console, which continues to do well in the market for Sony.

Announcing its latest earnings report for the first quarter end for the fiscal year, the company revealed that it has now shipped a total of 63.3 million PlayStation 4 units worldwide. The figure was previously 60 million in the last quarter, meaning that Sony moved 3.3 million units between April and June.

It is important to note that the company is talking about PlayStation 4 systems shipped out to retailers. It does not necessarily translate into units purchased by consumers. However, Sony has been enjoying remarkable success in that aspect as well. During the Electronic Entertainment Expo (E3 2017) in June, the company confirmed that the sales number was 60.4 million worldwide.

However, the year-over-year performance rate has dropped by a bit. Sony shipped 3.5 million PlayStation 4 systems during its first fiscal quarter last year. In light of the current forecast, the company expects to ship 18 million PlayStation 4 systems by the end of its new fiscal year. This is down from 20 million for the last year.

Operating income suffered a bit as well, registering ¥17.7 billion from the ¥26.3 billion earned during the same period last year. According to Sony, the drop is mostly because back then it had a “highly profitable first-party title” to help with sales. It is a likely reference to Uncharted 4: A Thief’s End.

Overall revenue for the company’s gaming division, which includes the PlayStation family, actually jumped 5.4 percent year-over-year to ¥348.1 billion. Sony stated that the improvement was due to better PlayStation 4 software sales along with contributions from PlayStation VR.
