Admitting that first party software for the PS2 launch was weak, Masatsuka reveals "That remains in the development division as an area of regret. We gain motivation with the thought that we cannot repeat that."
Discuss"Gamers will be able to actually play the PSP at the September Tokyo Game Show. This will be the first place where gamers can get their hands on the system, so rather than concentrating on how many first party titles are being developed for the system, we'd like to show what kind of software is running on the system as a whole." For this reason, Masatsuka comments, SCE may not have ten first party titles on display at the show as previously promised.
Following TGS, Japan can expect the launch of the PSP followed by Christmas and New Years pushes for the system. "We must consider carefully which games to release at which time," says Masatsuka. Expanding on the system's release schedule further, Masatsuka states "Looking at things broadly, the fifty-nine titles that were announced at the PlayStation Meeting will see gradual release until March of next year.
