It looks like it might be re-using things from the earlier two games, like the Skeleton enemies. It seems like they're using the same technology to make this game, too. It's a shame they hold such confidence in the engine introduced with Dawn of Sorrow, but as long as they're trying to advance the series with original game design, I've no problem.

The areas seem to be incredibly varied in this game. It shows the main character finding herself at Dracula's Castle, but I doubt that's going to be the only place in the game she goes. She's shown to go to a town, a forest, as well as in what looks like a shipwreck. I'm betting that the first area will be the shipwreck, then it'll go to town, then it'll go the forest, and then Dracula's Castle. There was an area shown in the trailer that looked like the main character was trying to break in to someplace. The areas besides that all could very well be in Dracula's Castle itself. We saw variety like that in the other Castlevania games. Then there's another thing. Where that huge crab boss is (that gets Elevator Faced), the outside world looks purple. When the outside looks purple, it normally means you're in another world, like in Harmony of Dissonance. That orange cave area also reminds me of Harmony of Dissonance.
