Speaking with Japanese tech site Gigazine (as translated by Andriasang), a PlayStation representative reiterated that NGP will support the growing list of PSP games available in digital format from the PlayStation Store. Unsurprisingly, Sony has no plans to develop an attachable "UMD reader" for NGP (despite filing a patent that leaves open the possibility), and the UMD-to-digital "good will program" has been dead for 16 months now.
Gigazine does report that Sony mentioned plans to re-release original PSP games on the NGP's new game media (flash memory-based cards), though the representative did not detail the possibility further. Certainly, it would be a no-brainer -- even if card-based re-releases could generate some "ill will" from existing UMD owners -- and the expanded storage size of the proposed new card format suggests that old PSP games could be sold in single-card collections or added to NGP game cards as bonuses. Or how about PSP re-releases with "NGP" treatment? Admit it -- you'd buy Peace Walker again if dual-analog and touch controls were added, not to mention some MGS4-ish graphics.
