On a quartlrly basis:
Q1 - Kirby, Mario Party 11
Q2 - Fire Emblem, Nintendogs 3
Q3 - Yoshi, Pikmin 4, New Super Mario Bros 3
Q4 - Mario Tennis/Golf, Animal Crossing 5, 2D Zelda,
??? - Retro's Next Game(?)
I'm guessing Mario Party 11's release window based on the cycle ND Cube seems to have made with the series. Nintendogs 3 is due to how the Switch's nature as a touchscreen-centric machine would make it ideal for a new game. Pikmin 4 is based on the assumption that it'd be made by the same team as Pikmin 3, which has not had a major release since Super Mario Maker. I'm guessing NSMB3 will be from the NSMB2 team. I'm guessing a new Zelda based on how 2D handheld titles have previously been used for experimentation. Mario Tennis is based on the assumption that Camelot will have some HD console experience from Ultra Smash and the better part of two years to make a fleshed out product (for once).
In general, I don't think this lineup is TOO unrealistic, and it would give Nintendo a good balance and rate of releases. Note that besides Yoshi and NSMB3 both being Q3 releases, games in the same window are fairly distinct, with the most casual-styled games (Mario Party, Nintendogs, and Animal Crossing) all being fairly spread out. Furthermore, I think that Animal Crossing could potentially be a flagship holiday title, at least in Japan. Maybe Retro will fill in that last spot? Regardless, Nintendo would have about one major release every 5 weeks or so.
I don't think Metroid Prime 4 or Pokemon will be ready before 2018. We'd actually have more than a logo for the former, and the latter would be a very fast development considering how Ultra Sun/Moon would have barely been released. I also don't think we'll be getting a new Mario RPG soon, between Color Splash's recent release and the SuperStar Saga remake.
Love and tolerate.
