A teaser trailer was shown for it at the Tokyo Game Show:

Alucard? He'd be the popular choice if they want to get all of the Symphony of the Nightheads to buy the game, I guess. Personally, I'm a fan of the 3D Castlevanias, but some might take offense at Alucard starring in one after such a stellar 2D game. But then, it hasn't been revealed if this is a 3D or 2D game yet, so I guess it's up in the air. I'm hoping for 3D. Leave 2D to the DS.
It'll be 3D. Unless they plan to release it on XLBA/PSN which seems pointless what with the DS and Castlevania always doing well on it. So, at least I'm hoping it's 3D. And though the other games weren't that great, I still enjoyed them to some degree, so I'm kinda looking forward to it.
Eh, I'll keep an eye on it. Doesn't register as high on my radar as Order of Ecclesia, though. WHICH COMES OUT NEXT WEEK WOOO YEAH
