^ Ah, it appears I misunderstood you. My apologies.

Perhaps the concept for Crypt Hydra was revealed at a point in time when people already knew about the game before its release - like how we're getting info for MHX right now. Maybe they didn't like Crypt Hydra because they were comparing it to the more "realistic" monsters that were already confirmed to be in the game.
