I was actually kind of curious about one more 3D run from IGA. Judgement raised a few good ideas that would benefit a full 3D title. Specifically the comboing ability and combat in a whole (minus the silly/dumb moves like Simon's spin dive). Apply this to a 3D adventure setting and I think you have a great game awaiting. The platforming is all that is left to prove really for 3D Castlevania, and would be the biggest question I'd have left.
