Both Naughty Dog and Insomniac have passed on dev duties for the Sony NGP's Uncharted and Resistance games respectively.
Instead, Uncharted for NGP is being handled by Sony's Bend Studio, the developer responsible for the PSP's Syphon Filter series and the Resistance: Retribution port.
Nihilistic Software will take on development duties for the NGP Resistance title, meanwhile. Nihilistic is also currently working on PlayStation Move Heroes.
