"Brawl Preorders (which are well over 1m!)"
well over 1 million? The only thing is i'm not sure judging by that topic whether he means over a million in NA+Others or just one. Even if we assume he means both that means about two weeks ago there were "well over a million" preorders. If more people preordered and you count the ppl just showing up and buying without a preorder this could be interesting....
