I wholeheartedly agree with Darc.
Since some of us do want a Castlevania from some group without Iga, why not give KCEK (GBA Castlevanias, N64 Castlevanias) another chance at an original, current-gen Castlevania project? 2D or 3D, I don't mind, as long as it comes out well.
I'd like to see a 2.5D Castlevania with detailed 3D modeling and landscaping. So, the terrain could actually flow in different angles yet still be sidescrolling like Viewtiful Joe, but it'd be even prettier than FFCC. And by using a 3D engine, realtime cutscenes would be easy to implement.
