Why will it be a system seller?

Because like Wii Sports, it's the type of title that people will play at their friend/cousin's/grandkids house, love and want to buy a Wii to play themselves.

Wii Party will be a huge hit software sales wise but it will do little to move hardware. Pokepark may move a few consoles. Metroid Other M should reach a million sales, but also won't be a hardware mover.

The key titles that will drive momemtum of hardware sales are Kirby and (especially) Donkey Kong Country. Being a popular franchise that has been put to sleep for almost 15 years, there is going to be a lot of pent up hype for this title similar to NSMB Wii, and it will move similar numbers to what NSMB Wii, though not quite as many. Kirby is also still a very popular Nintendo franchises, and 2D sidescrollers as a successful genre, so the game should drive momentum too, though not near as much as DKC.

I doubt Wii will have another record breaking 4.3 million in America in one month this year, but DKC and Kirby could push it to close numbers, perhaps something like 3.5 million.

I am almost certain that these titles will boost software sales for the Wii during the last third of the year. We may see titles released earlier this year gain more sales near Christmas, such as Super Mario Galaxy 2. I predict that Wii Party and Metroid: Other M will be best-selling out of the six. Metroid: Other M has large potential to be the best selling Metroid game, surpassing the 3 million mark.

DKC will be big, mark my words.

Kirby won't do much. Sure it's a 2D platformer, but it's expermimental and quirky, not a mass market game.

DKC, Epic Mickey, and Zelda: Skyward Sword will be the big momentum pushers for Wii out of all the games we know about.

I think Wii can sell 20 Million this year with thhose titles going into the Xmas Season and why? Theres something for everyone.Like we were told at Nintendo's E3 Conference

Thanks to conduit 2 goldeneye 007 epic mickey and donkey kong country half my mates are getting a wii       i think some old gamers will pick the wii up for all the 2d games coming out

It's going to be a good holiday, although even with all these titles I don't think 2010's Holiday sales will outpace last year. There's just no beating a 2d Mario game.

Wii Party looks like it will be the biggest seller. It also looks like it will be fun as opposed to something like Wii Music, so it will be a bridge game that could appeal to the expanded market and the core market in the same token. 10m lifetime sales

Kirby Epic Yarn certainly looks like another game that will appeal to the expanded market and core market. The only thing... Kirby has never been a megaton franchise like Mario. It sells well, but 10 million is well beyond the fan base. 4-6 million.

Donkey Kong Country seems like it will be this year's New Super Mario Bros. I believe it has the best chance of getting in touch with the old-school gamers and even the expanded audience. 9-10 million.

FlingSmash might be a flop, which is a shame because it actually looks like a fun game and seems to be an interesting, new intellectual property. I just wonder how much confidence Nintendo has though since they barely seem to talk about it. There was not a single mention of it in their e3 presentation. My initial guess is 500k to 1 million.

Metroid Other M seems like it will sell in-line with the previous Metroid games on the Wii. The preorders suggest that this game may have 500-700k WW sales in it's first week. This leads me to believe it will be at 1 million lifetime sales.

Pokepark has already been released in Japan and Europe, and has sold 300,000 copies so far in those countries. Based on these initial numbers, I think it will reach 1 million lifetime sales. 

Hey Let's not forget some pretty big 3rd Party titles are coming!

Disney Epic Mickey is shaping up to be a huge game. I think this game is going to be bigger than we expect. Perhaps 5 million .

Goldeneye, The real worry is Activison. Will they give this game enough time and money or are they just looking to cash in on the Goldeneye name? My gut tells me they are going for the "cash-in". But I think this game has a good shot at 2 million lifetime sales anyways. 

NBA Jam definitely looks like it could be a surprise hit. It has the retro arcade thing going which belongs on the Wii. It is also a 4-player multiplayer game certain to have that "party game" quality that will appeal to Wii owners. 1 million

Sonic Colors looks like it will be in line with many of the other Sonic games currently on the Wii, so 1 million  almost seems likely unless it's just a complete mess.

I hope wii sells over 14M this year.  With those titles it shoudl easily do it,  each of them should sell over 1M.

So in America 3.5 Million Wii Sales seems fair?
