Maybe you've never heard of Lunar: Silver Star. It was originally released on the Sega Saturn in 1996, then received a proper "collector's" version in 1999 on the PlayStation 1. 

So why's this news now?  Rumor has it that XSEED will be bringing this masterpiece to the PSP in the future. Right now, there is no release date - but the promise of a portable version is awesome enough to announce it now. Of course, PSP owners with modded firmware have been able to enjoy the PS1 version (and other PS1 games) for some time now. I know at least one Christmas list that this game will be going on.
