Firmware version 2.0 is being released tomorrow for the Japanese PSP. It includes a web browser and some enhanced video codec support (and support for AAC audio amongst other things), but it may not allow full res video to be played from the memory stick. I am between 2 minds as to whether or not I should upgrade. It seems that video files will require a new file naming structure, so I am not sure if anything I have put on my memory stick so far will still work after the upgrade. I know there won't be any answers to these questions until after its released, but would appreciate it if anyone finds a review of the new firmware on the net could post a link here.
