Kirby 4 million. It will get superb reviews.

Donkey Kong Country 6 million.

Kirby - 2 million

DKCR - 4 million

EDIT: Just looked up DKC's sales and HOLY SHIT, now I think DKCR might sell 10m at a push

Kirby 2 million

DKC 3 million

I don't think Kirby and DKCR will pull in the casual market like NSMBW did.  Also, the casuals just bought a multiplayer 2d platformer last year, which most probably havn't even finished (I havn't either) so Kirby and DK will look like more of the same but not as good.

They will sell well to the Nintendo fanboys and sell in numbers similar to previous installments.

My guess

Kirby:EY - 2 - 3m

DKCR - 5 - 6m

Wii Party - 20m

Kirby: 2M

DKC: 7M

Kirby will flop badly, with 3.5 million (remember that's a flop for Nintendo)

Dk, it's hard to predict, I see it selling 6 million - 10 million

Kirby 1.5-3 million

DK 3-5 million

it somewhat depends on marketing. Give kirby a cool comercial expressing its uniqueness and i think it might sell 4 million easy. DKC might depend on how many older gamers remeber DK and how many newer gamers will give it a try , but then again nintendo will market that too and that will sell 6 million easy.

Kirby: 1M. too quirky and strange to become a sales phenomenon. it will sell similar to the last wario platform game.

DKCR: somewhere between 6M and 8M. DKC was huge back in the snes days, but i feel that due to donkey konga/barrel blast, etc. his fame is kinda weakened. it won't do NSMBWii numbers but it will sell well.

Kirby will be a monster in Japan, it will do at least 1.5 million, maybe 2 million.

Worldwide Kirby will do 3.5 million.

Donkey Kong 6 million, 7 million being too optimist.
