Well, GameDaily BIZ likes numbers and we weren't satisfied with having nothing but a dollar total. We got in touch with one of our corporate contacts at a major retailer who told us that generally for every four standard copies sold, two limited edition copies and one legendary edition is sold. If that breakdown can be applied nationally for all outlets selling Halo 3, some simple math can yield unit amounts on day one for the three different SKUs and thus a total units figure.
