游戲網站Eurogamer.net發佈了一段PSP-4000的流傳, 提到將有機會取消利用UMD來運行多媒體的功能(如電影/游戲). 他們並提到新一代的PSP-4000將會在今年末推出, 有興趣可看來源網站. 這些消息都尚未由Sony官方證實, 還是有待時間來驗證吧.

The next iteration of Sony’s PSP handheld will feature a sliding screen, will no longer carry a UMD drive and will allow shoulder button-only games to be played when the screen is in its ‘closed’ position.

That’s according to a development source close to Sony, speaking to Eurogamer on condition of anonymity. We first broke the news of a new update to the system late last year, revealing that PSP-4000, the third incremental hardware revision of the console, is planned for release later this year.
