PS Vita software lineup planned to 2013

Sony launched the PSP in March 2005, and one criticism that was leveled against the company during that window was the system's dearth of new games. With the PlayStation Vita having launched in Japan last week, Sony Worldwide Studios president Shuhei Yoshida does not plan on having the company make that mistake again.

"In the past we launched PSP and then shifted our attention to PS3 when that came on the horizon, which we now concede was a mistake," Yoshida said in an interview posted to the PlayStation Blog. "So with PS Vita we are working on this huge range titles and planning ahead for a constant supply of excellent games."

To that end, Yoshida said that Sony Worldwide Studios has "a fairly firm plan right up to 2013." The Sony executive noted that any changes to the schedule will only be additive, noting that the system allows developers to quickly release smaller titles such as Escape Plan and Sound Shapes.

Yoshida also briefly addressed the PS Vita's Japanese launch. Citing retailer data, Yoshida said Hot Shots Golf was the most popular of the 24 games available at launch. Bend Studios' Uncharted: Golden Abyss took the number two slot.

Earlier today, Enterbrain reported that 321,000 PS Vitas sold during the first 48 hours of availability in Japan. However, the launch wasn't without hiccups, as Sony Japan issued an open letter to gamers experiencing hardware malfunctions, specifically calling out system freezes, upside-down screen orientation, and PlayStation Network connectivity issues.
