After reading THIS
article detailing Nintendo Power's coverage of Castlevania: Lords of Shadow - Mirror of Fate, I can say my apprehension is much lower and I'm on board so long as the information is correct.
Here are the good points:
-Trevor and Simon are both playable, along with two other characters.
-The Belmont featured in one of the screenshots of the Nintendo Power article is swinging with his whip a la Indiana Jones or, more pertinently, Simon Belmont in his Super Castlevania IV incarnation.
-It will be styled after the DS Castlevanias, with 3D segments added; that's okay by me so long as it's mostly a Castleroid.
The combat system and overall look of the game are looking to be a lot like that of the Griptonite Spider-Man games, and the space-time warping in which you take control of different characters in their respective places sounds extremely Shattered Dimensions-esque. I'm not sure how I feel about that yet; but, like I said, if the rest of the story checks out I'll be happy with it.
article includes a few other points as well.
