Actually, he might have been referring to the arena that was planned in Windhelm. There's coding for pieces of that arena left in the game, like the npcs, but the actual arena never made it into the game. I think it's reasonable that they put a tidbit into Cicero's book and left it in after they scrapped the actual arena.

Or, I could be way off.
