The Mii costume was added between Ryu and Cloud, and the
interview where he mentions that it should be Lloyd came out in February 2016. What's interesting is that in a
previous part of said interview, he says, regarding Cloud,
"A number of people fixate on the fact his original game was never released on a Nintendo console, but if we were to limit our choices to characters who appeared on a Nintendo console, we’d end up with Bartz from
FFV or the Onion Knight from
FFIII—how would that work?"
So I don't think Nintendo appearances were a big deal when he said that about Lloyd.
Also get Project X Zone 2, it fixes a lot of issues with the original and it's a fun time.
