Sony reckons it will sell between 2.5 million and 3 million PlayStation Portable handheld video game devices this holiday season. The company is going to try to double the installed base between now and the end of the year.

The company also said it would begin offering a PSP Giga Pack for $299. The PSP bundle will hit stores in time for the holidays and include various accessories such as a 1-gigabyte memory stick, which can store about 30 hours of music. Sony will continue to sell its $249 PSP Value Pack with a 32-megabyte memory stick which holds the equivalent of one to two albums of music.
