Sony is also facing increased competition from the exploding game market on tablets and smartphones. The iPhone 5, with its expanded screen and upgraded processor, will launch Friday in Japan, also drawing attention away from the game show.
The electronics company has launched a new initiative called PlayStation Mobile to bring its PlayStation brand to the growing army of Android devices. The program guarantees that certain "PlayStation Certified" devices meet certain hardware and software specs for a strong gaming experience, and will launch in the fall in nine countries.
Sony said Wednesday that it has added Sharp and Fujitsu, dominant mobile phone makers in the Japanese market, to the program. It has already signed up others such as Asus and HTC to the program, which also includes its own phones and tablets.
The company also announced a bevy of upcoming games for Japanese and international markets, including Soul Sacrifice, an in-house title for the Vita.
