Kirby could be released before Yoshi since it appeared in the Direct and Yoshi didn't, you're right. The reason for Yoshi being january and Kirby march on my list however is because Kirby's planned for a spring release and there's still no game announced for january and february. We also got like 30min of Yoshi gameplay at Treehouse e3 2017, so Yoshi could be closer to completion and Nintendo just might not have been able to make more than two trailers for Yoshi (e3 2017 + launch) due to it not having enough new gameplay ideas to make another one. The game is probably more about only one big idea so an extended gameplay fits more than a few trailers which would all show the same concept.
Of course this is an optimistic list, but I think some (if not most) of it like summer Animal Crossing is likely to happen, maybe off by a month or two. I don't know what to think about Sakurai's teased new IP (he said that he uses this http://nintendoeverything.com/wp-content/uploads/vifam.jpg for his current work, more precisely that its rifle is related to his next game somehow, I don't really see a lot of Nintendo IPs that would fit so yeah, i guess he's working on a new IP) though.
Also, do you think a 2D Zelda could release this soon after Breath of the Wild and Ever Oasis? Those games were made by the two studios which are the most likely to develop a 2D Zelda and both games being released this year. I don't know to what extent ALBW team from EPD 3 was involved in BotW's development so...
