Stephen King has announced on his website that his newest novel will be titled 11/22/63, and it will be published on November 8, 2011. Here's the book description:

Jake Epping is a thirty-five-year-old high school English teacher in Lisbon Falls, Maine, who makes extra money teaching adults in the GED program. He receives an essay from one of the students—a gruesome, harrowing first person story about the night 50 years ago when Harry Dunning’s father came home and killed his mother, his sister, and his brother with a hammer. Harry escaped with a smashed leg, as evidenced by his crooked walk.

Not much later, Jake’s friend Al, who runs the local diner, divulges a secret: his storeroom is a portal to 1958. He enlists Jake on an insane—and insanely possible—mission to try to prevent the Kennedy assassination. So begins Jake’s new life as George Amberson and his new world of Elvis and JFK, of big American cars and sock hops, of a troubled loner named Lee Harvey Oswald and a beautiful high school librarian named Sadie Dunhill, who becomes the love of Jake’s life—a life that transgresses all the normal rules of time.

My first response: What a hackneyed idea! Time travel, the Kennedy assassination, and that perennial King standby, the Maine setting. And it's even got a late-era King trope, too: The character who suffered a traumatic injury that left him forever changed. My second response: Stephen King sometimes does his best work when he's fucking with cliches. My third response: Hopefully, it'll be better than Under the Dome. That book held it together almost all the way through, but the ending completely destroyed it.
