Smash is the most popular fighting game in the world. It's also on a system that offers virtually nothing in the genre. There's currently no reason for a fighting game fan to own a Wii U. Smash changes that and opens the Wii U to an entirely new audience. So that's why people are excited for Smash, it's the world's most popular fighting game series and the only way you'll get to experience on a home console is the Wii U. It's going to pull a disproportionately large number of hardware sales compared to anything else Nintendo could release, because its core audience has so little overlap with the current Wii U audience.
On the topic of Mario Kart 8, it's not done selling yet. It almost single handedly doubled Wii U sales, and continues to sell well even so long after its release. The Support Nintendo is giving it is also amazing. A large new DLC pack and an amazing MK8 bundle for the holidays is just going to make it surge again for the holidays.
