If it can run them ... sure why not. The XBox One is getting FFXV, why not NX.

Just a question of can the NX run the game.

that was just a rumor from a guy who works with unseen 64.

After this conference i'm convince about Kingdom Hearts 3 coming to the NX not sure about 15 though.

I feel the same, FF hasnt really been apart of the Nintendo fam since the original games, but KH on the other hand despite the 3 main games being PS, feel very Nintendo~ish.... if that makes sense :0

Knowing Nintendo its not unlikely.

that is making a huge assumption... NX being a home console.

I remain unconvinced of this. How long has the 3ds been out for? how long has the wii u been out for?

which console successor is more likely to come out first?

the DQXI making it's way to the 3ds successor makes sense, not for a new home console platform from Nintendo with the added cost of development to a 0 people install base

To be fair I believe the Final Fantasy producer said he wanted to see Final Fantasy on the Wii U before it launched. Poor sales of the system probably deep sixed that. Final Fantasy hasn't been Playstation exclusive for like ten years now either, lets also remember that. If Microsoft can get FF games, Nintendo should too. It's just an issue of hardware power and the system not tanking. 

Was there any given date (Year) on KH3 release date?
Because if the NX releases before it, then Maybe (Dont even know what the NX will be)

If the NX is powerful enough, I don't see why it can't get both of them, FFXV and KH3. FF games are not exclusive anymore, and I think that KH3 fits a lot in a Nintendo console. But let's see!

Because if the NX was solely a handheld only it'd have BC and be able to play the 3DS version next year on launch, they wouldn't need another version.
