To clarify, while adding stealth in a Castlevania isn't a 100% dealbreaker for me, it certainly on paper seems jarring and totally out-of-place, especially in an action/platformer, and I don't see the need for anyone of us to make excuses for it such as "dracula needs to avoid sunlight ((despite according to cox the game taking place in 1 night))" or "why not add other gameplay genres to the mix the more the merrier guys." I don't want to have to worry about being in an annoyingly long puzzle segment (which I'm sure there'll be an abundance of) while at the same time adding stealth elements to it, only because "why not?" I'm not entirely convinced that just because an enemy doesn't see you or waits to attack you right away, that constitutes as proof of stealth in previous CV games. As of right now, I don't see how adding stealth gives any more layers of depth to the game, not anymore than adding QTE's or clumsy Collosus fights to LoS1 made it a better experience instead of just shamelessly tacking it on because it worked for that ps2 game so why not here. I could see the same logic being used, "it worked for MGS so why not here?"
Still, no gameplay videos yet, so it's just too early to make a definite decision. And considering the game is only 2 months away, that's kinda worrying. If we're lucky then we'll only see Dracula for whatever reason sneaking behind a few ledges for only a small small portion of the game. Otherwise I really don't see the point [other than obvious Kojima/MGS homage, which there'll no doubt be bucket loads of anyway]
