Today's Survey Target sounds like the old bounty system from MH Dos, and the Priority system from MH Frontier.

Limit Breaking sounds like they bring back the further upgrades back from MHP3rd, were you could use Armor Spheres to upgrade your weapons a bit more to give them extra Raw, or more recently the Honing system from 4U.
