1) The teaser, for me, was okay. I mean, it was meant to tease, and I believe it did. At least we know their going to use an amazing font.
2) If it were up to me, I believe that they would use embossing, because, practically every major (and minor) deck produced has embossing. And, D&D's last deck had it, so why not do it on this one. Right?
3) Is it just me, or, after you confirm your email, they bring you to D&D's Facebook page.
4) Also, with that teaser pic of the double D's (hehe), I highly doubt (in fact, I am positively sure), that it's the S&M, or even a deck box at all. As someone quoted, D&D said that they are releasing something they've, and no one else, has ever done before. So, I just can't wait to see what their going to be having.
EDIT: - It just reached my inbox about an hour ago. - Maybe it's a part of a seal or the centerpiece to the back design.
