I get what what OP is saying as that: if MK fails, nothing more will help. The games is actually doing well on the preorder chartz, and the game manages to sell on first sigth, a thing that not even mario manage to do. Yet, zelda don't do so well in japan(MK ahs a better worlwide appeal), and wiiu will recieve a version of smash 5 months later than 3DS. so, the only one running freely rigth now is MK.

Yet, there is no TV spots and the bundles is actually more expensive, so i don't know if nitnendo is doing all they should.

It's because those other Karting games are SHeeeet. Face it, Mario has a monopoly on the Karting genre.

But hey, obviously Pokemon only sells becuase Digimon and Monster Rancher no longer exist.

It's more expensive because it has an additional wiimote and wheel.

Who cares how much it sells when the console its selling on is dead...Anyway stop reframing the argument. The title of the thread is "Wii U rides on Mario Kart". The point is can Mario Kart can save the Wii U? The average person doesn't care for it, so it won't save anything. 

Will it "save" the WiiU ? Nah, it's probably too late for this. But you clearly underestimate this game. It is going to push hardware by a huge amount like very few other game can do.

Nope I doubt it will because the only people who care about Mario Kart are the ones who already care about Pikmin/Donkey Kong/3D Mario etc so they will already have the console. That ultimately is Nintendo's failing- to appeal to a large audience rather than a small, but dedicated, group. 

So you believe Mario Kart 8 wont push any hardware at all then? Are you sure you wanna say that?

But i bet would sell more if they cut the extra wiimote and bring the price to $280. For me, nitnendo rigth now just want to recover from the losses so far, not make the machine a sucess.

Referring to a system that has yet to recieve its biggest system sellers or reach mass market price as "dead" robs you of any trace of credibility you may have had.

Actually no, wait, your delusion that Mario Kart isn't a widely loved and highly popular franchise already did that.

Pikmin/Donkey Kong/3D Mario are game I am interested in. Still, they didn't make me buy the system. Mario Kart 8 + free game definitely will.

You can argue that I may be the only one but the hardware bump we will see at Mario Kart release date will say otherwise...
