Following the development of Uncharted 2: Among Thieves, the leadership at PlayStation-exclusive developer Naughty Dog decided to split its studio into two teams . The teams are fluid, and they often go back and forth between projects as needed, but this allowed Sony’s most important studio to work on two projects concurrently. This structure gave us the fantastic Uncharted 3: Drake’s Deception in 2011, and arguably PlayStation 3’s best game, The Last of Us, in 2013 With Uncharted 4 in development for PlayStation 4 , it begs the question if these structure is still intact, and if Naughty Dog is still developing two games at once. The answer, according to an interview Naughty Dog’s co-presidents gave to Game Informer , is a resounding yes.“We definitely have another project on the scale of Uncharted in very early pre-production stages,” Evan Wells told the magazine. “We have the sizable team that it takes to get something like that off of the ground, but it's got a long runway in front of it. We have a lot of great ideas and some stuff that is already getting everybody jazzed and excited. So, it's a long way off before we can really start talking about it in detail.”Wells further confirmed that the newest revelation out of the studio – that The Last of Us leads Bruce Straley and Neil Druckmann are leading Uncharted 4’s development -- shouldn’t affect the production of the second, still-unknown game.More tantalizing is the prospect of what this project could be. Could it be The Last of Us 2, a game Naughty Dog has been contemplating making ? Could it be a return to an old Naughty Dog IP, like Jak & Daxter, a franchise Naughty Dog already tried to revisit ? Or is it something new entirely? With Naughty Dog likely to laser focus on Uncharted in the coming couple of years – at least publicly – it’s unlikely that we’ll know for some time. Still, it’s exciting to think about what developers at the studio could be brewing in private.
