You are giving Blizzard too much credit in thinking we will even see him again. I love Blizzard but they are notorious for brushing characters under the rug or just outright forgetting about them. Remember Mal'ganis? He was a damn prime candidate to show up back in ICC after how his questline ended in Icecrown yet he just faded into obscurity after that. And now we will probably never get closure to him because the main damn person he was tied to is dead.
And he is a MUCH more important character than Ariok. He all but led Arthas down the path he went on. Sure the Lich King was really the mastermind but Mal'ganas was the conduit.
With Ariok I think we should be able to save him and turn him back to normal. That would be the best conclusion I think.
Your sausage (and many other things) would meet much darker fate than just not remaining intact
How about instead we learn that garrosh had a baby with....anduin ? Basically anduin was a girl all along but she was pretending to be boy to make daddy proud. And only her late mother and babysitter knew.
I would be really suprised if Blizzard didn't forget this guy.
6.2 SPOILERS!
Ariok is alive! From the sound files, it sounds like Ariok was held captive by Kilrogg and they attempting to push the demon blood on him, but he resisted and we help him escape. I think he might be involved in the Kilrogg fight.
You just lost The Game
