Just received my Proto (white base) -- very excited, but I noticed that mines does not have "NS" on the base, unlike like Leo's pictures.
In any case, the carbonium topsheet is just gorgeous.
I have the black base and it also does not have the NS as seen in other decks. I seem to vaguely recall when I toured the NS factory early this year, they commented that they were having some challenges with that part and that the final design may change. Then again, my memory maybe faulty.
