From converstations with people it seems that the primary selling features of the PS3 are its media capabilities, playing SNES games on an emulator and the ability to easily steal games ... None of which translates to high software sales.
Low software sales has two effects, it limits the number of games that are developed for you platform (and the PSP has one of the smallest line-ups of announced titles with somewhat solid release dates), and retailers make their money on game and accessory sales and don't want to sell platforms that don't sell software.
Whether you're ready to accept it or not, the PSP's sales are going to be way down in 2009 and down even further in 2010 (potentially gettin pulled from store shelves).
