Really, though, I'd rather play most of those games on my PS3 on a big ol' TV. Sony's finally making my dream come true with the "PSP Remaster" series, essentially HD'd versions of older PSP games. Sony's partnered with Capcom right out of the gate with Monster Hunter Portable 3rd HD Version.
News of these upgraded PSP games originated out of Japan, but the official press release (stating it's "starting in the Japanese market") definitely makes it sound like something we'll see rollout worldwide.
What's cool about the "PSP Remasters," however, is the ability to move between your PSP and PS3 without much trouble; the saves are compatible with one another. Plus, there's 3D support. Er, okay.
Look for more news on this at E3, obviously.
