Sony has officially announced that US and European release dates for the handheld Playstation console have been pushed back until 2005 while the company prepares more and better software for the console.

Expectations are high for the PSP, already touted by PlayStation guru Ken Kutaragi as "the Walkman of the 21st century" for its ability to play games, movies and music.

In the meantime, a release date for the Japanese market doesn't seem to have changed and the console could be making it by the end of the year there.
