Many of us have been curious to see just how Illidan would look when he was actually in-game as opposed to data-mined from the PTR client and then previewed through the WoW model viewer. Well, several brave souls from the PTR have managed to locate him in the Black Temple and have sent back the above screen shot of the
man Night Elf-Demon himself in game. The reports are that he's roughly as tall as Onyxia large, but not overly so, yet extremely imposing when you're standing face-to-err ... hooves.
The rumor from the peanut gallery says that when he gets to 20%, he despawns saying only "A terrible and costly mistake you have made. It is not my time, mortals."
