I really hope they lose 404, or mocap, its a bit of a waste. Just add an extra accelerometer and a few fiducials across the device, it would accomplish the same thing and possibly more. I don't like it, they had a chance to do something great, and they made that thing that looks like a scepter. I feel like this is something my sorc should have held back in the D2 days.
