Sony has defended its decision to launch the PSP handheld gaming device in Europe much later than elsewhere. The PSP is set to be launched with a "killer price" for Europe, says Sony. Arse. The PSP goes on sale on 1 September, six months after it hit US stores, and nine months after its Japanese debut. Speaking in Los Angeles, Sony Computer Entertainment Europe's Phil Harrison said the decision was made to ensure there would be enough in the shops. The PSP is a multimedia portable games device, with built-in wi-fi, that can also play movies and music. Sony unveiled the games line-up for the handheld's European launch at a press event in Los Angeles, on the eve of the official start of the Electronic Entertainment Expo, E3. The show is the world's largest video games event in the world. A total of 19 games will be available for the PSP when it goes on sale in Europe in September. Dozens more are expected by the end of the year, including a version of the hugely popular Grand Theft Auto series. [BBC News]
