You could extrapolate the sales and get pretty reliable numbers if you wanted to.
Ie, 10% of X360 SKUs are the Arcade packs. Therefore you'd have 90% being the Elite/Pro SKUs with the games.
Either way, it's not a big deal. The X360 doesn't need bundled software charted here to overinflate sales: it already dominates everything else.
Back from the dead, I'm afraid.
