As per this news. The novel is titled Anathem, and the blurb follows:

Since childhood, Raz has lived behind the walls of a 3,400-year-old monastery, a sanctuary for scientists, philosophers, and mathematicians — sealed off from the illiterate, irrational, unpredictable “saecular” world that is plagued by recurring cycles of booms and busts, world wars and climate change. Until the day that a higher power, driven by fear, decides that only these cloistered scholars have the abilities to avert an impending catastrophe. And, one by one, Raz and his cohorts are summoned forth without warning into the Unknown.

Peter Berg is directing a Dune adaptation. Well, that’s a thing. I haven’t seen any of his movies… no, wait, I saw The Rundown, which was mildly amusing. Possibly thanks to the Walken. Maybe they’ll cast Walken as De Vries, and Dwayne Johnson as Duncan Idaho, and Seann William Scott as Feyd-Rautha? Nah, I don’t like where that went either.

Not the sole creator of D&D, not the most important figure in the industry, but sine qua non. The original report is here. Troll Lords was his current publisher, so this is very unlikely to be a hoax. There’s also confirmation here.

Sad news.
