One thing I noticed in the trailers is that the Lords of Shadow seem to have animalistic themes to them.
For example, one of the ominous towers Gabriel looks upon has a ton of crows swarming around it, and there is also a shot of a flying demon forming out of what also appear to be crows, ala the now-standard Vampire Bat boss. The pendant Gabe shows to a villager has some kind of ram head design on it (possibly a goat? Would make sense, if they're going with animals associated with evil omens). And the huge-ass castle (perhaps Castlevania itself) is swarming with bats, almost certainly Dracula's animal of choice.
