Just want to know if FFXV is going slow in production another time will Kingdom Hearts 3 be affected by it or will it keep going now that Nomura focuses on KH3. Will Kingdom Hearts 3 development be affected in that case or not?

It won't

 

Kingdom Hearts III has its own team and Nomura's less than divided attention, while Tabata and a handful of other teams tackle XV

FFXV is actually going very well. It won't affect KH3 at all.

Can't call them a handful now, they've merged into one team with 200-300 people.

Nomura completely left the project to Hajime Tabata(who I admit is doing a better job than Nomura)

 

That allows Nomura to dedicate all his time to KH3

Not.

Um, it won't. In the past, it might have, but now that Nomura is focusing on Kingdom Hearts instead, the two projects will be able to proceed independently of each other. In a way they are still sister projects, but neither one will inhibit the other from developing. Basically, there's no need to worry about Final Fantasy XV being the main cause of Kingdom Hearts III's delay anymore.

KHIII was already affected by FFXV, but soon things will turn to KHIII's hand.

Nope. Both titles will move a bit faster in development since nothing will hold either back now..
