In terms of the family tree, Koller said that the PSP Go is not replacing the PSP-3000 but that both units will live in harmony on retail shelves -- although he did say that Sony likes 10-year lifecycles so the PSP Go should have a bit longer life than the PSP-3000. Still, Koller said the company plans to continue to support both downloadable and retail-based games. Belmont asked if there would be different games for the Go versus the traditional PSP; Koller responded that the units will have a similar catalog to begin with, but with time, he expects there to be some differences -- like maybe developers making smaller games that are shorter experiences.
