Capcom has indicated on a number of occasions that it will support Monster Hunter World with free post-release downloadable content. That includes the addition of new monsters to hunt, the first of which we now have some details about.

Monster Hunter World releases for PS4 and Xbox One on January 26, followed by a PC version this fall. A final PS4 beta has just been announced alongside the release of a new trailer showcasing some of World's Elder Dragons. Capcom also revealed a limited-edition Monster Hunter PS4 controller and Starter Pack bundles, though those have only been announced for Japan so far.
