Now that I've recovered, I'm starting to think about what Nintendo might be planning for the NX's first calendar year. They are obviously working on major unannounced projects for the platform, but things are weird considering the lack of information and mysterious nature of the machine. So here are some guesses as to what Nintendo could have planned for the NX in 2017, with reasons why I think these ideas may or may not be plausible.
The Legend of Zelda (100%) - Virtually guaranteed. I wouldn't be surprised if this game was delayed to be a launch title, similar to how some say Twilight Princess could have been released earlier as a GameCube exclusive. Regardless, seeing how this is the one thing Nintendo is willing to make playable at E3 this year, I doubt they're going to delay it for too long.
Mario Kart 9 (80%) - These games have been released roughly every three years for a while now, and even if MK9's not playable at E3, it could still be available by Holiday 2017. Especially since MK8 did so well despite low Wii U sales.
3D Super Mario (75%) - There hasn't been one of these in a while, and they always do well enough. Heck, the 3DS showed that Nintendo is willing to launch a 3D Mario and Mario Kart within a few weeks.
Paper Mario: Color Splash (50%) - Remember in May 2006, when Super Paper Mario was announced for the GameCube, with a release date of October 2006? History could easily repeat itself. The main reason this isn't a higher likelihood is that Nintendo will at least try to salvage the Wii U's last holiday, since 2016 doesn't have a Zelda to save it anymore.
Splat2n (50%) - My guess is that Splatoon is for the Wii U what Super Smash Bros was for the N64: a great success in an untapped arena for Nintendo. And seeing how Melee came out less than three years after the original, I can imagine a similar time frame for Splat2n. Unlike Melee, there is no need to limit development to under 15 months. This franchise is a great sucess, and the only reason we wouldn't see a sequel in the near future is to give the second entry more time to cook.
Mario Party 11 (45%) - Mario Party is always going to happen. It's just a question of timing. And right now, I doubt that ND Cube has too many distractions.
Pikmin 4 (35%) - I suspect that Pikmin is in the works and will see a new entry for the NX. But I also doubt that this will be one of the first priorities at Nintendo EPD.
Super Mario Maker 2 OR New Super Mario Bros 3X (30%) - A Mario Maker ssequel's biggest problem would be taking advantage of all the existing content. That means using all those levels made for the Wii U, which could take some time to overcome. And although another NSMB is an obvious choice, these games don't seem to be particularly good as launch titles. Note that NSMBWii sold over 28 million after being released halfway through the Wii's life.
Hyrule Warriors 2 (25%) - Has Omega Force ever stopped working on Hyrule Warriors these past few years? Even Legends can be seen as them testing the waters for new ideas and characters. And more seriously, this could be released a few months after the main Zelda and include its characters and environments for excellent timing.
Luigi's Mansion 3 (15%) - There have been rumors about this, and Dark Moon was a big hit. It could happen!
Metroid (2%) - As If!
Love and tolerate.
