Update: As promised, firmware 4.01 is now available for download on Network Update. We’ve included a direct link to the update below if you wish to install it manually.

Sony’s Eric Lempel, director of PlayStation Network operations, has sent word that firmware 4.01 is scheduled to be released soon. The update will include two main changes, the latter being improved video playback for certain file types.

* Display of search results under Internet Search has been improved for certain languages.
* Playback of video content under Video has been improved for certain file types.

Would be nice to know which file types. Does this mean DivX and XviD format files will finally be playable through the PSP’s built-in video player? Maybe, but if so, you’d think Sony would at least mention it, instead of vaguely stating that compatibility has been improved. Either way, we’ll find out for sure when the firmware is released.
