I'm really looking forward to this.

This is speculation on my part, but... Since the Rathalos is much smaller than normal, and they were trying to steal an Egg (which hatches at the end), I assume that the Rathalos is a juvenile, and you can use Eggs to hatch new monsters as mounts.

I hope that you can ride a Yian Garuga. That would be cool.
