If you go back and look at any remaining XP or Vista boxes even the older versions MS never overdressed any of them to start with. PC game manufacturers spend far more time in that direction dressing up the boxes like "eye candy" to be more appealing even if the game turns out to be dud!
MS tends to use a standard formal type appearance for each version since it's the contents that really make the difference. You see that quite often with any office type or utility software sold in an office store if not at your local Walmart or BestBuy. The experienced user is looking at what the software itself will do not what the box looks like.
