^^^While its unlikely we can never rule out the possibility of subspecies being added back into the game. Secondly, Fatalis doesn't have any subspecies. Crimson and White Fatalis are not considered subs, merely Fatalis that are older and are in later stages of life. Seriously, check the subspecies page, they are not there. That being said, all 3 can come back in MHXX regardless of whether subspecies return or not.
