Lets get somethings clear here:
FFvXIII was originally a ps3 exclusive, SE rebranded it as FFXV to get it on the PS4 and XB1(Which they expected to have a larger market share + dev costs of their engines was tanking them, which is also why they made 3 ffxIII)
FFXV would definitely be a downport, thus we have the problem of porting costs vs expected sales. Not to mention the game would face heavier competition on the Wii U from Bayo2 and X.
In Regards to Kingdom Hearts III, the numbered Kingdom Hearts have never been on Nintendo platforms, and SE is making multiplatform again because of money.
However, since the 3DS game is the closest in terms of story to 3, one could argue that it has a nintendo fanbase, but thats a strectch cause not every 3ds owner has a wii u and numbered kh never go to handhelds.
