Several games were outlined in a recent post on MCV. Assassin's Creed creator Patrice Desilets is working on a title called 1666. With a date like that I think it's fair to say we're going to be seeing plenty of fire and plague. We'll call that an educated guess.
Darksiders dev Vigil are working on a game with a working title of Crawler, Relic (currently rubbing polish into Company of Heroes 2) are working on a title called Atlas, and Turtle Rock Studios (the team originally behind Left 4 Dead) are making a game called Evolve.
