Could Naughty Dog's acclaimed post-apocalyptic action game The Last of Us come to the PlayStation 4 some day? "We'll see" is the message Naughty Dog told a fan who asked that very question on the PlayStation Blog recently.

"We're just getting our Naughty Dog engine up and running on PS4 as we work on the next Uncharted project," Naughty Dog community strategist Eric Monacelli said. "We will see what the future brings! :)"

This response is more hopeful than the one Monacelli provided in October, when he bluntly stated that Naughty Dog has "no plans" to bring The Last of Us to PS4.

The Last of Us launched exclusively for the PlayStation 3 in June 2013 to widespread acclaim, and it was our 2013 PS3 Game of the Year selection. The game has shipped over 3.4 million copies.

Naughty Dog has at least two internal development teams, though the company's only confirmed project--outside of new DLC for The Last of Us-- is the new Uncharted game for PS4. Monacelli said gamers can expect a "full reveal" of the game sometime in 2014.
