I wonder if ridding Alucard of the bloodlust has anything to do with the Belmonts loosing the ability to wield the VK. I'm thinking something like Alucard biting Richter, or Richter using his blood to seal away Alucard's bloodlust. Take the curse into himself, or something. IGA wasn't kidding when he said he would find some way to explain why the Belmont's have to forfeit their right to wield the VK until 1999. At the least, I thought he was going to approach it through a manga, but it looks like we're getting the real deal. I hope IGA pays this much attention to the 1999 events(whenever he decides to address it).
