Jokes about the dark lord aside, I genuinely hope that Konami is taking their time on the next two games (DS and whatever console--probably 360--they're working on), so that we get something more epic and classic-feeling. As restless as we are, we Castlevania fans will wait for quality.
Better graphics (more in terms of artistry than technical prowess), better stories and characters (no more time travelers and kiddie humor), better gameplay mechanics, more details, more goodies and extras, more fan service; take your time Konami.
