The system is primarily geared to those who didn't buy a Wii U (everyone). So I would expect Zelda and at least one other key new title at launch. Then a series of upgraded ports from Wii U, like Smash, MarioMaker, MarioKart8 and Splatoon. These could be "full" versions with all DLC + visual upgrades, or possibly sequels but I expect the former. They will have Retro's new game and a 3D Mario from EAD Tokyo within the first year.
I also expect FF15 to be a launch title, and a few other 3rd party titles. I expect most major third party games to be there for Christmas 2017. They'll be hoping for a good start to sales and the associated userbase to make a positive impression on third parties.
