Oh hell yes! I just spoke to my dealer. As of last Friday, I too am in D status. He has one ahead of me, in E status. He said D = scheduled, and E = frame, so that's consistent with the above post.
He said that if anyone tells me that they know when my car will be delivered, they are speculating. He said that the factory is awaiting some sort of certification, prior to being allowed to ship finished product. If they finish any Vipers beforehand, they will sit in the factory and wait until factory certification.
