The $30 price drop isn't exclusive to GameStop/EB Games--it's universal. But, that's not where the savings end. Sony has also added two more games to PSP's Greatest Hits lineup: Daxter and Syphon Filter.
According to the press release, "We have always been passionate about making great entertainment accessible to everyone, and the new price for PSP, as well as the continued growth of the 'Greatest Hits' library, reflect our ongoing commitment to supporting and expanding the PSP community," said Jack Tretton, president and CEO, Sony Computer Entertainment America. "We are pleased that we are able to engineer savings for the consumer at this stage of PSP's lifecycle, allowing more individuals to experience PSP for the first time. In particular, we have recently seen a steady rise in the number of teens adopting PSP as their primary handheld entertainment system, and we expect the new price will accelerate that trend."
Sony also reminds players that the future of PSP is quite bright, especially with the upcoming God of War: "Ready At Dawn couldn't be more pleased with our success bringing Daxter to the PSP platform last year, and now we have another opportunity to blow away expectations of what a developer can accomplish on a portable when Kratos hits the 'small screen' in God of War," said Didier Malenfant, co-founder and president, Ready At Dawn Studios. "PSP is an ideal platform for us to work on because we have a high level of freedom to be creative, and we can deliver gameplay experiences that rival ones you'd get from a computer entertainment system."
[Update: According to Engadget, the PSP Entertainment Pack will also receive a $30 cut, from $250 to $220.]
