Ok so this just popd up now, still doesn't confirm anything. (See bold)

In an event attended by our friends at Eurogamer Spain, Naughty Dog's Arne Meyer delivered a presentation in which he confirmed the graphics toggle.
By default the game runs at 1080p60 in single-player and multiplayer, but the addition of the 30fps lock may indicate occasional drops below 60. If you are locked at 60 you get no judder. If you aren't, you do get judder (or tearing), and so locking to 30 produces a more consistent experience (for more on this subject, check out Digital Foundry's article "Do higher frame-rates always mean better gameplay?").
