@TigrexJeff I think he's talking about the Lava Whale Dragonator at 2:27-2:28 http://www.youtube.com/watch?v=wSwhrNBmaQ4

If you ask me I think it may have something to do with the story like,when a huge threat is discovered threatening a village or afew villages after defeating Goa Magara,they decide to make it to assist the hunters while fighting the beast.

Now with the Manda-like Monster,I also say it could belong to the Snake Dragon species/class but,we most likely won't know until afew days or weeks after MH4 is released.
