There is a supposed leak from an "insider" about the Nintendo Switch. It mentions a ton of info which may or may not be true.
Specifically for Square Enix support
I'd say it worth paying attention to this. The FF anniversary event is just around the corner, if the Dissidia Versus title is correct, it's fair to assume at least some of the rest are as well.
Personally, I still think 2017 is unlikely for KH3

Specifically for Square Enix support
Square Enix is providing HUGE support to Nintendo Switch. At launch, they are going to bring to retail Dissidia Versus: Final Fantasy, a port of the arcade game to the Nintendo Switch. They will also work with Nintendo to release a series of high quality Final Fantasy Amiibo figures throughout 2017 that will work with Dissida Versus and future Square Enix games as part of their Final Fantasy Anniversary Celebration. Dragon Quest XI: Sugisarishi Toki o Motomete will come out in Japan in the Summer and will be brought over to the USA in 2018. Holiday 2017 is the big release as they plan releasing Kingdom Hearts III to all platforms including the Nintendo Switch which will also have a special bundle. Square Enix also plans on bringing Laura Croft GO, Gunslinger Stratos SWITCH, Puzzle & Dragons Battle Tournament, A Realm Reborn and Dungeon Of Zaar to the Nintendo eShop on Switch in 2017. In 2018, Square Enix plans to release Bravely Trinity, the third game in the Bravely Series and will be the first (provided there is no collection at some point) in HD exclusive to the Nintendo Switch.
