I was just going on the assumption that he would eventually be tied to Summoner in some way in the future since he has been a Summon in past games and is becoming one in XI eventually, I would think maybe in the new expansion, since they announced him over 2 years ago and recently released footage of him in action...

Since the one from XI looks exactly like the concept art from XIV I was drawing my own conclusions. Mainly all I was saying is that no matter what they use him for I hope he looks like the concept art and use the cartoonish looking one in the second pic as just a pet, not what we will see in the story or as a summon or whatever role he eventually has...
