This really comes off as a parity issue. Same will probably go with Kingdom Hearts III. That's really sad if true.

How exactly does this situation suggest parity?

It's something he said in another interview:

" The full game will be optimized for each console, though they haven’t decided if both console versions will be exactly the same once optimization is finished."

What is there to decide if not enforcing parity or not?
