Like I always assumed from the beginning. The first revision "PSP Slim" (PSP-2000) was the true and only revision that was needed. The PSP Go was more targeted for new owners rather than existing. More like a beta to see if the market would generate hype and some share.
I truly think sales wasn't the main target but feedback from the hardcore crowd was. So that if they were to make another revision or successor, they know what to incorporate.
