A Sony official has said the TV-capable new PSP will be available on time, but only in black.
The company said the cables will be available in the U.K. on September 14, as scheduled - but conceded that the "ceramic white" model of the hand-held will be delayed.
The PSP Slim and Lite will launch in black but the white version will follow in October, a Sony spokesman has said.
While outpaced in sales by its competitor, the Nintendo DS, the PSP features a large LCD screen and UMD movie playback capability, as well as interactivity with the PS3.
The TV cables will allow the newest versions to be hooked up to a television.
