I'm very much looking forward to this, Metroid style games are probably my most loved type of game (is there a name for this genre yet?). Even though the traditional anime art style of DoS and PoR didn't bother me much (I actually like traditional anime art styles more than traditional western art styles) I'm glad they're returning to the um I dunno... gothic anime? Art style of SotN, HoD, LoI, CoD and AoS. It just seems to work better for Castlevania (funny thing is when SotN first came out I hated this art style and I wanted RoB's anime style back). I don't think the art in this game is being done by Ayami Kojima though as it looks different (looks like something between her style and DoS and PoR's style).
In any case, is there any word on exactly how the glyph system will work? I've seen it constantly mentioned in some previews or "eyes on" of the game but never really elaborated upon.
Well I've heard that Shanoa (that's the girl's name, not sure if it's been stated here yet) can use a glyph with both her hands and her back. If you use a glyph with either of her hands it becomes a weapon (meaning SotN's dual weapon system is back) and if you use it with her back I assume it's probably used as magic (haven't heard this yet though). Glyphs are obtained from enemies.
Something though is puzzling based on earlier previews and something Iga alluded to which is in regards to some form of Wii connectivity in the game. On the one hand I do hope that it means there is a Castlevania on the way for Wii, but wouldn't be surprised if it was an extra sort of thing kind of like how Daigasso Band Bros. 2 will have some speaker application you can transfer to the Wii as a sound output channel or something to that effect.
Well when they signed up the copyrights for this game's name they also signed up for the name "Castlevania: Judgment". Most people are speculating that this will be a new console CV game that focuses on the 1999 incedent (although most people think it has to do with that simply because of the word judgment in the name, even though it'll probably end up named Castlevania: Rhapsody of Judgment or something). I think I heard somewhere once that IGA would consider making a CV game for Wii if he could figure out a way to make whipping with the wii remote less taxing on the arm so you never know.
EDIT: Hmm I just thought about it and a 1999 based CV game would make sense to be the Wii CV game since as far as I know in the current known canon Julius Belmont is the only Belmont not to have a game and unless they plan on making a remake (IGA stated once that he would like to remake CV3) this is the only chance to make a Wii CV game with a character that actually uses the Vampire Killer (unless they use another Morris) which if they made I'm pretty sure would be the main gimick.
EDIT2: I noticed that the mobile phone game was named Castlevania: Order of Shadows. I wonder if this game will have some sorta story continuity from that game since their names are so similar (Order of Shadows and Order of Ecclesia, kinda makes me think of Aria of Sorrow and Dawn of Sorrow).
