Probably fuck it up the ass.
Here's the thing though, Sony's always talked about how they couldn't do a handheld, battery technology wasn't there, yada yada yada. But now they have made a handheld, and everyone assumed they'd just made it a design concession that it couldn't use up too aweful much power.
Instead Sony worked around the problem, giving developers control (through libraries, though I'm sure Sony would require approval) of the battery usage. All launch games obviously would need to be at the lower end of power consumption, it is after all a portable and battery technology is still too limited to allow portable gaming as powerfully as the PSP's hardware could peak out at. The future option is there however, and as the quote from Namco said, very much up and coming. You can play these higher power consumption games at home when the system is plugged in, or on shorter trips, and alternatively play the low power consumption games (and probably emulators) on the go.
Seems less like Sony cripped the system and more like made it what all future portables should be, a truely versitile entertainment device that you'll use daily regardless of where you might be or what you might be doing. At home, on a short trip, or on long excursions, the PSP should have games with battery life lengths suited to all three. And when better battery technology comes up in the next couple years Sony won't be left in the lurch with old hardware, instead they'll just make all games at maximum clock speed.
My only gripe is that Sony would then need to make it mandatory that all games list expected battery life on the back of their cases, if not on the UMDs themselves, so that you know what games are best suited for what situations.
