This deal has interested me as well. From my understanding of the deal (please correct me If I'm wrong) it seems that there is the xbox 360, guitar hero 2 game and wireless guitar, 2 wireless xbox360 controllers, and the additional 2 bundled games.
If you look at the guitar hero 2 combo on best buys site currently, it shows that the bundle includes all of these items, altho each is listed seperately with a link to each.
If this is all bundled, I'm so there!
