I signed up too as soon as we heard, and I got my box last Wednesday too. In fact, I was carrying mine when I went to get the mail as I was going Christmas Shopping. Carried it the whole time and I probably won't send it in til after the 5th as I have a concert to go to and I'll darn sure have it on me then.
After that, I'll send it in.
So you should be getting your box and paperwork real soon.
