If NSMBU and Smash ports are true that makes
Bayonetta 1 + 2 (we'll count this as one basically)
Hyrule Warriors
DKC: Tropical Freeze
NSMBU
Smash
As 5 ports ... that's a fairly large chunk of the year as Nintendo does not like to release more than 1 game a month for most months. At some point you start to run out of release spots for all these games.
July - Yoshi
August - Fire Emblem
September - NSMBU Deluxe
October - Bayonetta 3 + New Labo?
November - Animal Crossing
December - Smash Deluxe
Maybe something like that. I don't think there's gonna be too many more releases, getting 2 Nintendo releases a month is something Nintendo doesn't like to do, it overcrowds things and 3rd parties need room to sell product too. We need to see if NSMBU on Switch is true I guess but either way things are getting tight release wise there's not many open slots left.
