lol @ all of you arguing about pack-ins.
1. Wii in Japan costs less than NA/EU. Why?
2. Whenever anyone figures the cost to produce a Wii, the game is factored in.
3. When other companies include a game, their prices don't reflect the added game, thus it's easy to see it as free. However, when N was pricing the, Wii Sports was part of that price. Otherwise, like Japan it would have been cheaper.

Face it, it has sold that much. Even if it is dropped from a pack-in, it will become the #1 selling game.

Well Wii Sports is what makes a lot of people want to get a Wii so Nintendo definitely did a great job here.

 For the life of me I can't think of any recent console that has had a pack in game within the first year of its life other than the Wii and Wii Sports and the PS3 and Motorstorm.

With the Wii, there's only one SKU and everyone that buys a Wii (in the correct region) gets Wii Sports so that's pretty important.  With the PS3, there are...a few skews so that cuts down A LOT of the potential huge sells from the pack in.

There have been random other pack ins in recent years with the DS and PSP, but those came much later in the consoles life.  I don't think Halo 2 was ever packed in with the XBox and I don't think the PS2 ever had a pack in game in America, though I could be wrong with that one.  Whatever the case, the pack ins would have come long after the initial boom of sales and that would affect the numbers getting heavily inflated.  Those late pack ins also suffer what the PS3 pack ins suffer in that there are options. 

Wii sports has recently clcoked over 100 hours of play for me X_X

just throwing that in there

I just KNOW the Wii wouldn't have sold HALF as many as it did without Wii sports as a PACK IN =)

@Profilcrab

You didn't exactly follow your sig :P

@Twroo.

Yeah, same goes for me, well maybe not 100, but at least 80. Pretty great tech-demo, don't you think?

i just have wii sports because i got a wii

plays it once in a while
tho

Wii Sports is the best selling Wii game in Japan

OMG, who cares, it's bundled with the Wii. Why are people surprised, as long as Wii sells (and the chances of that continuing look pretty good), then this game will sell. No big deal.
