Three former top employees of the studio responsible for PlayStation3 exclusives Uncharted and Jak & Daxter have been hired away by Valve, perhaps indicating that publisher won't be developing "stepchild versions" for the PS3 anymore.
Naughty Dog has lost Vitaliy Genkin, Alex Vlachos, and Elan Ruskin to Valve. Valve's been critical of developing for the PS3 and open about their dissatisfaction with The Orange Box port, saying before they return to PS3 development, "we need to be able to support it in the right way." Three top guys from a Sony-owned studio would seem to provide that kind of support.
