The combination of digital and UMD software has proven problematic for those seeking to build a permanent PSP library.
But Sony has often said they've learned many lessons in the portable world, so when it comes to their next handheld (currently named the Next Generation Portable), things are going to change. SCEE president Andrew House delivered some good news via MCV :
"One thing we learnt from PSP, is that we want to have simultaneous delivery in digital and physical for NGP. Just to clarify that, all games that appear physically will be made available digitally."
As for the current state of the PSP and its downloadable and physical-media games, it might be best to look towards the future. The NGP should be quite the unit, and while I will always have a preference for physical media, perhaps that's just something that shows my age.
Simultaneous digital/physical releases for games, though? We're down with that.
