Astro,
Pokemon Diamond/pearl in America: 4,4M
Wii play America: 4,3M
Combined versions of Call of Duty: 3,7M
Wii play Japan: 1,5M
Pomemon Diamond/pearl japan: 1,1M
Call of duty Japan: less than 200k
Wii play europe: about 2,5M
Pokemon Diamond/pearl: about 3M
Call of duty both versions europe: about 2M
No way Call of Duty was the winner... According to worldwide weekly, it has sold about 6,2M across all versions.
Nintendogs (in its third year) did about 5.4M.
Pokemon Diamond/pearl did about 9M
Guitar Hero for all versions did about 6.7, 0.3 more than CoD4.
They must be talking about console game, excluding Wii play and Wii sports and only on next gen consoles. IMO that is meaningless.
