You know what would be sad next year is the 5th anniversary of 1.5 coming out and we still don't have like a proper trailer or release date for Kingdom Hearts 3. I know games take time to make but damn. Still have time though.
Nomura has more than one project. He used to have Versus XIII/FFXV to worry about as well until I think 2014. It's only natural for it to take so long when he has so much on his hands.
