Here's my theory based off of several other theories I've read online. Here's what we tell about the Arkham Knight.

1. He's male, based on the physical build.

2. He has skills similar to Batman.

3. He is younger than Batman, hence why he refers to Batman as an old man.

4. He has the resources to fund a private army.

5. He's wants to kill Batman.

6. He believes that the Gotham can't be saved, only cleansed.

I know this theory has holes, but I believe the Arkham Knight is Anarky. Think about it. Anarky wanted to cleanse the city of corruption, but Batman stopped him. This could be a possible motive for wanting to kill Batman. As for his age, he appeared to be around 15 years old in Arkham Origins, give or take a few years. Since Arkham Knight takes place about 7 to 8 years after Origins, Anarky would be about 22 to 23 years old, much younger than Batman. Also, alot can happen in 7 to 8 years (Batman himself trained in slightly longer timeframe), which is plenty of time for Anarky to bulk up, train, and accumulate resources; the latter of which he's more than likely receiving help with, perhaps the League of Assassins. We also know that Anarky is going to be in the game as his signature tags have been seen in gameplay demos. Perhaps his army, or a faction of it, is continuing his work, possibly under the impression that Anarky is dead or that he abandon them. Again, I know it's not the best theory, but it's the best i got.
