I don't want to repeat what others said, so here were the week #1 sales for Guitar Hero 3 last fall: (http://vgchartz.com/aweekly.php?date=39390&console=&maker=&boxartz=1)
1 Guitar Hero III: Legends of Rock (360)
Activision 1 658,671 658,671
2 Guitar Hero III: Legends of Rock (PS2)
Activision 1 454,596 454,596
3 Guitar Hero III: Legends of Rock (Wii)
Activision 1 271,053 271,053
Current American totals for GH3:
1 Guitar Hero III: Legends of Rock (PS2)
Activision 3,312,641
2 Guitar Hero III: Legends of Rock (360)
Activision 2,522,705
3 Guitar Hero III: Legends of Rock (Wii)
Activision 2,326,271
360 sales are always heavily front-loaded. 360 sales for Guitar Hero 3 even managed to outdo PS2 sales in the first week, and the PS2 version went on to sell 800k more units overall.
If anything, GH Aerosmith demonstrates the opposite point, how much ground the Wii has caught up relative to the 360 in the past nine months.
End of 2008 totals: Wii 42m, 360 24m, PS3 18.5m (made Jan. 4, 2008)
