Can't hardly be the final trailer given they have 3 more months to market the game. Also we did get a second trailer a few weeks ago so I'm guessing it's probably some new collaborations/deviants/returning monster or two.

A western announcement is also unlikely given it's a Japanese announcement. For that we would have a Nintendo Direct like where Monster Hunter Generations got its announcement.

Exciting nonetheless.
