If it wasn't for the fact they needed to finish female hrothgar, then DawnTrail and the FF# title and things associated being brought over to 14 would've been the clear point and time to add Burmecians. Even then, it would still be nice to see Burmecians in the future.

If we ever went back to Hingashi, some small Tanuki-like race would would be fun as an original option. But we'll see in the future.
