Whatever it is they are announcing it seems to be newsworthy enough that the New York Times is going to be printing an article on it.
Though, honestly, it doesn't have to be very big news for the NYT to have a little puff piece on it in a relevant sub-section of the paper. It could be 5e. It could be an MMO. It could possibly be re-releasing old product (on the outside). Some significant "brand" activity is also possible (saturday morning cartoon! TV show! videogame! movie! new novel line! whatever!).
It could also be huge, but I don't imagine even the hugest thing for D&D (like being sold, or even 5e) would register as a more than a blip to most of the world at large. So I'm betting on an NYT piece that's in some media/movies/tv/books/whatever sub-section of the paper, something interesting to the world at large, but only maybe a 50/50 chance of it being something interesting for those who are playing the PnP game.
But, hell, I was wrong about Dark Sun.
