American sales: Halo 2 vs. Halo 3 vs. Nintendogs vs. anything on Wii

[Freestyler]

Nintendogs is selling over 30,000 a week in the US, over two years after release. This is unheard of, maybe except for Pokemon. Nintendogs still manages to sometimes get into the top 10 in sales (in slower weeks) which is amazing.
