EDIT
Rise of The Argonauts looks good. I'm wary of getting too excited... The trailer comes across as a mixture of Shadow of Rome and God of War with some superb graphics and what looks to be some deep fight mechanics. I'm not one for Space Marines but have a love of Greeco / roman history and mythology so this game could be right up my street.

Legendary is another. This one is set in contemporary New York and plays on the opening of Pandoras Box, unleashing all kinds of beasts on on to the world. It's a FPS (from what I can tell) with the monsters actively hunting you out if you try to hide.
The graphics don't look as polished as RotA but hopefully the gameplay will more than compensate.
