I have to admit that I am so surprised by the strong developer support for the DS over the PSP. As of November 30th, 2006, DS had sold about 26 million units, while the PSP had sold about 22 million units (worldwide, source: Wikipedia) - not that much of a installed base discrepancy. Furthermore, the PSP is, at first impression, a more desirable machine - despite the higher cost, it has (by comparison) lovely graphics abilities, and far more storage. Sure, it has loading time issues, but these could certainly be fixable if the developers were willing to address them (of course, I haven't worked for the PSP, so perhaps that's more difficult than I make it sound). Why the strong developer support for the DS, then?
