Some notes to the trailer:

That's all I found on second sight. Did you notice something else?
 * 1) Did anyone see the moving sand at 0:22? Could that be a Nibelsnarf or even a new (Horseshoe Crab-like) monster?
 * 2) A new mechanic where you can hit your own friends with Hammer/SA/GS upswing and he can attack from above. (if this wasn't already in/seen at the Red Khezu part)
 * 3) Nerusukyura Subspecies uses Paralysis with its spikes, Kechawacha Subspecies Fireballs and Zaboazagiru is the new Blangonga/Barioth (normal form Ice area, subspecies desert).
