Take five people from each of their most talented studios and make them come up with PSP games in 6 months to a year. I'm talking 5 people from Naughty Dog, Santa Monica, Media Molecule, Sucker Punch, Slant Six, Quantic Dream, San Diego studio, London, Cambridge, Liverpool, Guerilla Games. Make them some talent to boot. I bet you would find interesting games in quick succession. Those studios are large enough to lose a little talent and still thrive. Give PSP the software backing it has always needed. Put your A gamers on the system because western 3rd parties aren't seeing success.
PS Advertise the GAMES! and how low cost high quality they are.
