During Sony's the financial conference call for investors and analysts, Chief Financial Officer Hiroki Totoki gave some interesting details on the performance of PlayStation's games.

First of all, we learn that the video game business was the primary factor in the significant increase in the revenue forecast for the whole company for the full fiscal year.

The yearly forecast for PS4 software sales was revised upwards due to the fact that God of War by Sony Interactive Entertainment Santa Monica Studios has "significantly exceeded expectations" alongside some third-party titles. On  top of that, the games revealed at E3 "are receiving strong feedback."

First-party game hits were identified later in the call as the primary factor for the upward revision in profit forecast for the Game & Network Services segment. Third-party hits are also a factor. The contribution of third-party games was much greater than Sony's expectations.

Totoki-san also explained the reason behind the slight decrease in PlayStation Plus subscribers during the last quarter. He mentioned that the difference isn't major, but during previous quarter hit multiplayer games were released causing PS Plus subscribers to spike, then the numbers naturally stabilized.

That being said, there are going to be releases of major games starting in September and October, and that might cause another expansion of subscriptions.
