Japanese electronics maker Sony said on Tuesday it will launch the new PSP in Japan on September 20.
Both Sony and Nintendo released their handheld gear, the PSP and DS, respectively, late in 2004. But sales of the PSP, which can play movies, music and games, have recently been outshone by the DS.

The new PSP will sell for 19,800 yen ($162), 5 percent less than the current model, which has been sold for 20,790 yen. It compares with 16,800 yen for Nintendo's DS Lite, the lighter version of the DS.
"The PSP is heading into its second growth stage," Sony Computer Entertainment (SCE) Corporate Executive Masatsuka Saeki told a news conference. SCE is Sony's video game unit.
Nintendo sold 23.6 million DS units in the year ended March 31, outpacing PSP shipments of 8.4 million, as its games such as "Nintendogs" pet training title proved a success and expanded gaming beyond young men to women and the elderly.
The DS has two screens, opens like a book and allows gamers to control play with a stylus, instead of manipulating a keypad.
At the E3 game industry exposition in the United States last week, SCE Chief Executive Kazuo Hirai said it would launch the new PSP model in September, but no specific launch timing or price for the Japanese market were available.
The game unit also said on Tuesday it would launch the latest version of its popular in-house racing game "Gran Turismo" in October.
"Gran Turismo 5" is one of the most eagerly awaited titles for the PlayStation 3 game console, and its launch ahead of the critical year-end shopping season is expected to help breathe life into slow PS3 sales.
The PS3, which made its debut in November, was outsold by Nintendo's Wii console by over three to one in Japan in the first half of 2007, according to game magazine publisher Enterbrain.
Its high price and scarcity of strong software titles have often been cited as reasons for the sluggish start.
The basic version of the PS3 sells for 49,980 yen in Japan, which is twice as much as Wii's price tag of 25,000 yen.
Prior to the announcement, shares in Sony, which competes with Nintendo and Microsoft Corp. in the $30 billion video game industry, closed down 0.9 percent at 6,350 yen, underperforming the Nikkei average's 0.12 percent fall.
