Star Wars Episode VIII gets a Title.

The title of the new Star Wars film was released. Episode VIII is going to be called "The Last Jedi". Does this refer to Luke or Rey? Is Luke the last ever or is it just a reference to the current state of affairs? In the openning crawl of The Force Awakens, Luke is  referred to as "the last Jedi". I guess we will find out December 15, 2017.
