i have been traying to find out more info on this since i like DD for my psp. Anyone has some link or something?

UPdate: i talking the entire librery of first party games

I don't know when it will happen, but I know Sony sure as hell ought to get it done.

I remember hearing them say that at some point all PSP games would be downloadable, which means your PSP becomes much more portable. No need to carry around cases for games you might want to switch to, and more battery life, because the UMD drive isn't sucking power.

thanks for the good news

According to this article, there is going to be a bigger push to get more psp and ps1 titles on the PSN store.

"The PSP revival is being led by three key factors: A resurgence in developer interest in the portable, a push for more digital downloads, and rumors of a new, sleeker model of the device."

"Besides attracting new games to the platform, Sony is going back through their library of old games, all the way back to the original PlayStation, to see which titles they can bring to the PSP. The titles they select would most likely be sold on the PlayStation Network, allowing gamers to download the game and install it on the PSP.

"We are making a concerted effort for digital distribution," he said.

Most triple-A titles coming to the PSP still use the proprietary UMD disc, but it may not be long before we start seeing more games go directly to digital distribution."
