New details from Thor: Ragnarok have been revealed through the official synopsis released by Marvel Studios:
In Marvel Studios’ ‘Thor: Ragnarok’, Thor is imprisoned on the other side of the universe without his mighty hammer and finds himself in a race against time to get back to Asgard to stop Ragnarok—the destruction of his homeworld and the end of Asgardian civilization—at the hands of an all-powerful new threat, the ruthless Hela. But first he must survive a deadly gladiatorial contest that pits him against his former ally and fellow Avenger—the Incredible Hulk!
Sounds like Thor: Ragnarok will incorporate details from Planet Hulk, but of course we already knew that.
Story by comics writer (and Planet Hulk creator) Craig Kyle & Christopher Yost (Thor: The Dark World) and Stephany Folsom, with the “screenplay by” credit going to Eric Pearson, the writer of the Marvel One-Shots Agent Carter, Item 47, A Funny Thing Happened on the Way to Thor’s Hammer, and The Consultant.
