Well, it seems to have just been confirmed. If you ask what has seem to been confirmed, it seems there are afew secret boss monsters in MH4 like other games and it seems one of them maybe "The Legendary Black Dragon" itself, Fatalis. I say seems because, so far there isn't anything supporting this yet but, its very likely since alot of MH games have done it in the past.
