I don't give a toss if it doesn't reach Mario Kart Wii levels of sales, it won't stop it being probably the best Mario Kart yet, and I will just enjoy it for what it is. Nuff said.

Hmm maybe, though I think it will do 6m lifetime.

I edited it. You took forever to post that...

And yes, Nintendo definitely will want to, at least before 2015's Holiday. It's also going to be heavily bundled.

Is that proof of Nintendo not believing their own product can sell on its own?

I asked the Magic 8 Ball if Mario Kart 8 would outsell Mario Kart Wii; it said no. Then I asked it if Mario Kart 8 would outsell Double Dash!!; it said yes. Seems as though it has sense...!

Don't think so. I could also see it outsell Double Dash.
Depending on bundling, I reckon it could reach 8m+ lifetime, eventually.

It's virtually doomed to that position because of the console it's on. So yes, i'm with you on this one.

Thats fine but thats not what u said. U said it would have close to a 100% attach rate in order to sell that much which is not true. Wii U would literally have to be discontinued now in order for it to not pass 6 million.

For the last 3 generations the home console version of Mario Kart has had roughly a 30-35% attach ratio. Assuming that this trend continues Wii U would need a lifetime install base of about 15-17 million in order for Mario Kart to sell 5-6 million. Im not saying this scenario is gauranteed to happen but its def a realistic number for both of those to sell based on Wii U current hardware and software sales.

You are Wrightfully wrong on this one!

Mario Kart 8 vs Mario Kart Super Circuit, this sounds like the bet of the ages waiting to happen.
