Asked specifically if owners of The Last of Us and the game's season pass will get a next-gen upgrade discount, Naughty Dog community strategist Eric Monacelli said on the PS Blog: "We're looking into the business model for all this and will post about this once we have input from all regions."
The Last of Us Remastered release date is being listed as June 20 2014 by multiple US retailers including Target and Best Buy. Priced at $59.99, the title will feature a number of improvements over 2013's PS3 original, with Naughty Dog targeting 60fps.
Studio co-president Evan Wells says: "The graphical fidelity has been turned up to 11, we've got 1080p, we're pushing the draw distances further, we're creating higher resolution character models, better lighting, better shadows."
Remastered will also include a number of The Last of Us DLC packs featured in the game's season pass, including the Left Behind single-player add-on.
