3rd party support for Wii is going fairly well.

Ghaleon.

Wii has something else than great 1st week sales, the games have legs.

For instance:
Perfect Dark Zero: 200k US alone first week. More than two years later - 900k.
Mass effect: First Week: 380k. Next 3 weeks: Less than 300k.

To opposition to this:
Launch sales
1) 66,939
2) 42,218
3) 41,832
Launch sales
1) 97,734
2) 74,776
3) 104,651
Launch sales
1) 89,616
2) 146,492
3) 200,224

Mario and Sonic at the Olympic games that is.

Of course, this isn't the situation with all Wii and 360 games, but 360 games have HUGE week 1-2 and Wii games have legs.
