It seems like there are different opinions on how many units of Forza 2 were sold because of bundles. I'm not that familiar with the Forza 2 bundles, so when did the game start being bundled, was it bundled with all 360 SKUs and when did the bundle end?
@ goddog,
That's fine for it to be your reason, but do you have any particular reason to think Forza 1 is under tracked?
