Sony Japan has announced that all upcoming first-party PSP games will also be available as a downloadable digital version, as well as a regular UMD release.

This will be available from the same day that PSP owners are able to get direct access to the PSP Store from their handheld rather than access it through a PC or PS3.

As with the direct Store access, the digital downloads have currently only been announced for Japan.

The first batch of downloadable titles from Sony Japan available before Christmas will include include Secret Agent Clank, Patapon 2 and LocoRoco 2.

And as you'd expect, there's no news on when we can expect such a privilege. We'll let you know as soon as we get any updates.
