So they dedicated about half of one of the trailers to Teostra, a monster who was already in MH4. I think it would be pretty dumb to build up all that suspense about what was attacking the town and then have it just be Teostra with some new dragonators. It's possible but it doesn't make any sense to me.

I'm still expecting a NEW final boss and maybe a hidden rare species but either way this is shaping up to be a pretty great addition to the series imo.
