Mario Party did better than I expected, especially considering the poor reception compared to MP9. And it's probably even better news for Nintendo, considering how a third of that game "encourages" people to buy Amiibo figures. I'm going to guess lifetime sales of 700k to 800k in the USA, which would make it roughly on par with how well most GameCube iteration sold in the region. It will never match MP8, but I doubt Nintendo will mind a lifetime total of over 1.5 million worldwide.
Majora's Mask on the N64 only sold 1.9 million in North America according to VGChartz. The 3DS version should sell 70% of that by the end of the year in the same region. And considering how the Zelda/Handheld combo is stronger in Japan and Europe in 2015 than the Zelda/N64 combo was in 2000, I wouldn't be surprised if the remake sells similarly to the original. Not a terrible fate after all.
I do not know when the next Smash Bros game is going to come out (I'm guessing the first half of 2020), but it is going to be available on any handheld device Nintendo has available. These American sales are going to place it between the N64 original and Melee in lifetime sales, which undoubtedly negated any resources or sacrifices for the Wii U version.
Smash on Wii U and MK8 are likely to surpass NSMBU and Nintendo Land as the best-selling games on the pplatform in North America at this rate, especially considering the ongoing support for the two games as free and paid DLC. MK8 is likely going to keep stronger legs as people go back to play it a year after release, and even something as simple as nerfing Diddy Kong can help convince people to invest time in Smash (and by extension the Wii U). I expect these two games and NSMBU to be the Top 3 by 2016, with Nintendo Land falling to 4th place at best. And even then, a surprise is more likely to hurt than help NL. Splatoon or Mario Maker could be a big hit, a new bundle could push 3D World past it, etc.
I wish Nintendo could sell more hardware, but their recent strategy of focusing on their own software with support to keep prices high and legs strong along with Amiibos to encourage collecting glorified action figures is working nicely. It won't make them a huge profit, but losses will likely be minimal at worst for the next few years, giving time for a possibly huge transition to take place.
Love and tolerate.
