I don't think so.

 Brawl might be 17 million as long as the Wii install bease grows to over 70 million which is quite likely

 The userbase for the DS is simply so much larger than any console currently...it just doesn't make any sense to compare them.  

Wii Sports
Wii Play
SSBB
SMG
Mario Kart Wii
Wii Fit

Will all be above Brain Training.

^agree - however, it will be close due to all the casuals

Honestly, I think it is impossible to predict how well any high profile Wii games will sell through out the entire generation ... So far, most of the big titles that have been released have passed their Gamecube version and just continued selling at a very steady rate; as an example, The Legend of Zelda: Twilight Pricess on the Wii is currently the 4th best selling Zelda game, will be the 3rd best selling game by the end of February, has a Gamecube version which has sold 1.5 Million units, and is still selling at a rate of (roughly) 40,000 units per week worldwide ...

Brawl's already at 850,000 in Japan, probably past a million by now. If you even took remedial math, you'd know that there is a good chance that it'll get to 2 million, or 3 million in it's life cycle, assuming it has poop for legs. If NA's 650,000 Galaxy sales launch week, and the numerous reports that Brawl has topped those pre-orders substantially, it's a safe bet to call over 1 million week one in NA, and something close in Europe. So if Smash sells 2.5 million (minimum) total in week 1 sales WW and you don't expect it to make a run for top selling game, then the crack may be having negative effects.

From your list only 4 or 5 console games can beat SSBB and still 2 of them are pack in games. No way 15 games will outsell SSBB this gen. 4 or 5 is the absolute maximum. I'm hoping we will see a new franchise compete with the likes of GTA and SSBB or Mario Kart though.

I'm talking lifetime sales. And I firmly believe Wii and DS will both outsell PS2. But they will do so because of a multitude of software, especially the new, disruptive titles. And so attach rates for titles like Mario, Zelda, and Smash Bros. will plunge even as sales increase by large amounts over last gen.

People's problem is when they believe attach rates will only fall by 5 or 10% as the install base goes up by 3, 5 and 6 times. Mario Kart DS is going to be the biggest MK yet, and I think MK Wii will beat that. But they still won't top 15M sales, while MK 64 did almost 10M on just 33M consoles. Certainly to an extent a low selling console holds back a top game, but to a much higher extent the totality of the software lineup holds back the console.

Both the increased install base and the increased hype will most affect the launch sales of the game, and in turn, yes, the legs will be shorter, though still significant.

brawl will become the most own game for the wii
it will have amazing legs because anyone that buys a wii will pick it up with brawl
it already had more pre-orders and bigger sold more in japan then galaxy
its also pretty unfair to use the ds where the install base is 67 mil and games are only 30$
Also lets face it brawl will have little competition on its platform for the rest of the year especially considering its genre
I dont see this games selling anything less than 15 mil so titles like ac: ww and smg wont sell more than it
